Hello,

TLDR: How to open all facebook videos in 1 PIP window, or/and auto-close PIP if video ends, or/and disable autoplay, or/and disable mute or just remember mute state.

I'm watching multiple short videos on facebook (without account) and I have few problems:

Videos are too small, but I can't switch to fullscreen, because I lose position, so I'd have to scroll too much every time, so the only way to have larger size is PIP, but I have the problems.

Another problem while playing videos, they start playing automatically, mute enabled, so I have to disable mute and rewind every time.

When I open 1st PIP window for 1st video, it's opened in large PIP window, but when I open 2nd video, it's opened in 2nd PIP window, next to previous, so I have to manually close the 1st PIP and move 2nd PIP, every time.

Perfect solution would be:

• disable autoplay for facebook videos
• always disable mute for videos, or remember mute state per session
• auto-close PIP window if video ends or open another video always in the same window

I already tried:

• google
• bing AI
• about:config option media.videocontrols.picture-in-picture.allow-multiple set to false and true, restart firefox
• other about:config options for pip

Is there any way to open all videos in the same PIP window and not in multiple PIP windows, using any option or even extension, please?
Workaround could be to auto-close PIP window if video ends.

EDIT: Now I have another problem, PIP button is not shown for each facebook video, even the same length, with the same settings, I tried to switch some about:config settings, change them all to default values, but PIP button is shown just for some videos, it looks random.

Firefox 116.0.2 (64-bit), tested with the Nightly 118.0a1 (2023-08-12) (64-bit), default settings without extensions, Windows 10 22H2 64-bit.

It looks like Chrome is going to add post-quantum key exchange X25519Kyber768 to secure TLS connections, see https://chromestatus.com/feature/5257822742249472

As much as I hate Chrome, I'd like to see such a feature in Firefox too. Any idea if there's a technical discussion/proposal somewhere?

Opera's new 'Tab Islands' feature is very cool and I've wished for such a feature in FF.

Briefly, "When opening new tabs from a webpage, those tabs are automatically grouped together into an island."

https://blogs.opera.com/news/2023/06/opera-tab-islands/

I happen to be one of those bozo users with hundreds of tabs open all the time and I'm always interested in any feature, addon, plugin, whatever that would make it easier to keep my tabs organized.

Anyone know of such a feature in FF?

Is there a way to see how much memory each Firefox Add-On uses? I've tried to look into "about:processes", and "about:memory". The first one tells you the total amount of memory used by the Add-Ons, and the latter gives you a 30,000 page long report that I don't know how to make heads or tails of. I KNOW my Add-Ons are eating up a lot of memory. I want to know WHICH ones are eating up the most so I can know which ones I should maybe shut down. Ideally, I wouldn't shut any down because they are all geared toward productivity. But maybe I can prioritize some over others.

Is there an easy way to view this information? Something akin to the Chrome web browser?

#firefox

In the latest Firefox version(116.0.2 (64-bit)) the button "List all tabs" won't show any tabs unless I close like half of them, then it works again if I open new random tabs. Currently 246 open tabs.

Any other way to fix this? I don't really wanna close those tabs.

The way I know this is that I tested in a sandbox with the same profile to try to find the problem.

EDIT 14/Aug/2023: So I just found out the issue was some tabs that had a " --" at the end of the title probably caused by some addon made this issue happen. It probably isn't really a - but I don't know what character is that.

All you have to do is just copy the url, open a new tab, paste the url and go. Close the previous tab with " --" at the end.
Just make sure you are not opening a new tab with CTRL+(clicking the + icon) from the "broken" tab with the " --".

Example.

Hope this helps someone else.

As title state, seems since 115.0.2 it disappear?

In the coming months Mozilla will launch support for an open ecosystem of extensions on Firefox for Android on addons.mozilla.org (AMO). We’ll announce a definite launch date in early September, but it’s safe to expect a roll-out before the year’s end.

I am in a bit of a pickle. I'm a developer, and I also use some crypto social media, and I also like downloading media sometimes, I do a lot of stuff. I modify CSS, I script & hack the web, yadda yadda. Basically what this means is I ended up with like 50 addons I juggle-enable-disable all the time. This is extremely frustrating without some kind of grouping them, or at the very least searching only among my installed addons to enable/disable.

Do you guys have any idea if a tool or method exists to solve this problem?

Tech support help?

Basically If i search for a term in the address bar such as "Cheese" and press enter. Then it'll hang for awhile, and not do anything. But If I press enter again, it'll show the google page result for cheese.

Just wondering if anyone else has this issue, because chrome doesn't do this.

116.0 (64-bit) is my current version

#firefox

Though the long wait is finally over. Firefox 116.0 ships with custom formatters support!

The main point of bringing custom formatters to Firefox was to allow the CLJS DevTools (custom formatters for ClojureScript) to work in Firefox.

Right now I'm on 117.0a1 and I only see the search term in the url bar, which is improper.
Is there am about:config toggle for this.
I have the default one URL bar view set.

Some more tech support, yeah :/

well, as to try to solve my other issue I’ve reinstalled Firefox on my iPhone, however, this has created more issues. Whenever I “restart”(drag at the bottom of the screen and drag the Firefox app up) Firefox forceboots me out of the app. This happens 50% of the time, aka every other time the app force boots me out then it just allows me to use it as normal. A side effect of this is that it keeps opening the oldest tab opened, instead of the one I was most recently viewing.

Is there any way to fix this? As I said before, Firefox 116 on iOS 16

As the title said I'm trying to customize my keyboard shortcuts with autoconfig.js, but I don't have much experience coding with javascript so I'm a little lost. The autoconfig.js solution was suggested in this thread (https://support.mozilla.org/bm/questions/1381773#answer-1517102), but the example they used was for a different shortcut. Specifically, I'm trying to change the private window shortcut from the default to ctrl + shift + n, but I wasn't sure how. If anyone could offer some guidance besides third party extensions it would be greatly appreciated 👍

I currently have a puny 380 tabs open that consume 42GB RAM on my MBP '21 Max whatever (with 64GB total, shared with the GPU).

I have gone through most troubleshooting and it's clear that the unload mechanism isn't achieving it's goal (I mean, aside from an absolutely psycho amount of tabs I am hell-bent on having to "come back to later"). The reason that these tabs are open and have been loaded is that I've been transferring my other browser tabs over and setting up my Containers & Sidebar Panels, so each tab would have to be open within the last week.

Question: Most of resources I've found online lead me to believe that all I need is to modify browser.low_commit_space_threshold_mb. But it's nowhere to be found. about:config on MacOS is just returning an empty value and offers me to set it. Dare I? Would it actually work?

And yes, the browser.tabs.unloadOnLowMemory is set to true and browser.tabs.min_inactive_duration_before_unload is a default 600000 (which is in ms IIRC, so it's 10 minutes)

My main issue is that even manually triggering the Unload from about:unloads doesn't help the situation, and it can't be that all of the tabs are using WebRTC or are somehow considered to be active? Can it be a side-effect of Sidebery extension? Surely not? Many of the tabs list "Last Accessed" datetime between 3-9 days ago and still have the Base Weight of 0, so that part probably works, but Firefix decides not to unload them?

--
Random thought: It would really help if people wouldn't need to chase this. I assume that the way that MacOS handles RAM with it's swap and whole "memory pressure" is probably isn't the most simple thing to work around but unless I can fix this it'll be very difficult to consistently use, and I can imagine people less inclined to figure things out be easily turned off. And yes, I didn't use to have this problem with the other browser with just as mental number of tabs.

Day 9 of (finally) moving away from Chrome after Web Integrity API proposal is going swimmingly, as you can see.

I get this error:

why is that? other threads loads without issues.
how to fix?

thanks.

I got an issue with youtube not recommending videos on firefox, i tried going to safe to see if it was an extension issue but it isn't, i tried in chrome if the recommendations was working and it did ( i did this when logged out). It just recommended the new trending videos that i don't like. I'm in firefox 116

Forgive if this is not going to be formatted well, I’m still very new here. Anyways

I run iOS 16 and Firefox 116. The problem is that sometimes all my tabs(even private one) randomly close. This is really annoying as I often open new tabs when skimming wikis. The only real answer I can think of is having too many tabs open, but this is ruled out since my most recent crash happend when I had 10 tabs opened. I really want to stop this from happening.

Thanks in advance!

I find these news quite disturbing:

https://lunduke.locals.com/post/4387539/firefox-money-investigating-the-bizarre-finances-of-mozilla

I'd like a keyboard shortcut to act in the same way as the toobar button "show sidebars":

• If the sidebar is open, it hides it

• If the sidebar is closed, it opens to the last used sidebar

This page, Keyboard shortcuts - Perform common Firefox tasks quickly only describes how to toggle individual sidebars. History, bookmarks etc. So depending what is open you have to use unique shortcuts.

Is it possible?

I <3 FF but they are really stingy about the keyboard shortcuts.
