Is there a way to move a tab at a Second window, back to a previous window? Basically, can I freely decide which tab goes onto which window, when I have multiple open as a way of organizing my immediate search history and browsing?

I have tabs that I can see using resources in the about:processes view but the value in the name field is something like "Firefox (8748)" or "https://fooSite.com". If I have a lot of tabs open, which I always do, it's not clear which one is causing the issue. It would be great if there was a way to show the url that is loaded so that one can quickly choose to stop it, reload it, or close it. Yes, the X action sort of let's you do that but you still don't know exactly which tab you are xing and it's only a kill switch for the tab in the end; there's no choice to resolve the issue by just reloading the page in the event of some video element that is consuming gpu for some reason. It might be a tab that I want to keep around. Making a little more meta data available so that a user can easily track down the specific tab would be great. Imagine I have 70 windows open... Yes, probably a corner case but it's the way I roll.

Problem:

       Firefox 137.0.1 on Ubuntu 24.04 fails to load vencord.dev with PR_END_OF_FILE_ERROR

       Other browsers (Chrome, curl) work fine

       Same error in Safe Mode

   What I checked:

       SSL cert is valid (openssl shows no issues)

       Reinstalled Firefox completely

       Reset profile, updated CA certs

       No extensions installed

   Technical details:

       TLS_AES_256_GCM_SHA384 cipher

       ECDSA-SHA256 signature

       Verification shows OK (code 0)

   Need help with:

       How to debug this specific TLS termination

       Where to find relevant Firefox logs

       Known issues with Firefox 137 and ECDSA

   Can provide:

       Full openssl output

       Firefox debug logs

       Packet captures if needed

   Quick test:
   curl works:
   curl -v https://vencord.dev
   Firefox fails even in headless:
   firefox --headless https://vencord.dev

   Tried forcing TLS 1.2:
   NSS_SECURITY_ARGS="version=tls1.2" firefox https://vencord.dev
   Same error

Dictation tools on AI platforms don't seem to work when the AI site is open in the sidebar.

This is the case when the AI site is open using the side view Firefox extension and the native Firefox AI sidebar.

My MacBook's dictation function works fine.

Via C > Users > User > Appdata > Roaming > Firefox > Profiles >x73axdaw.default-release> storage > Default I'm presented with my various website stored info. What I'd like to know is how via the files I can discover the relevant url if able. For example in the screenshot noclip.website is a valid url, other option not so.

Metadata doesn't seem to be helpful and can't find out a "target url" looking through other files.

Здравствуйте уже месяц не могу загрузить свое видео на ютьюб. жду несколько часов и прогресс загрузки видео ноль. Другой браузер свободно загружает видео. Браузер мозилла удалял и устанавливал несколько раз. Помогите пожалуйста с настройками.

Hello, I have not been able to upload my video to YouTube for a month. I have been waiting for several hours and the video upload progress is zero. Another browser freely uploads videos. I have uninstalled and installed the Mozilla browser several times. Please help with the settings.

Hi, strange things happening with Firefox of late. Eg, when trying to log in my mail on o2.pl with saved login/password, now the log in page loads and doesn't show the saved login, doesn't allow me to click in any box either (it previously did it flawlessly). When googling images, it only shows some images and when I scroll down it doesn't show more. Some pages won't load properly. "Content failed to load" on chatgpt. And miscellaneous other glitches on other websites. I have some tabs opened, I want to keep them, don't want to reset Firefox. The problems only appeared with recent updates. What to do? Best. W.

Why is it when Firefox Beta updates, pinned sites get deleted? The only other activity is that a private browser was opened. Still, why does Firefox delete pinned sites that were commonly visited? There is no recovery option. It is like my account was involuntarily removed from the memory. That is unacceptable.

Hi

I just rebooted my computer, and when I opened Firefox again an hour ago, all my extensions were gone (I've re-added those) but so are any bookmarks older than about a year. I'm logged in, and I don't have sync on. I'm not sure where to even start looking for them to get them back, but this is a huge pain.

Up-to-date Firefox on Windows 11 renders a page and later renders a blank page. Toggling Enhanced Tracking Protection will cause proper rendering of the page until it goes blank again.

I do not have this browsing problem when using Edge.

I'm thinking Firefox has a bug.

In the recent update, my add-ons/extensions from my toolbar menu were removed. The add-ons are listed and active, but I can't select them in my toolbar menu as I need them because they are not showing. Is this an update change or a setting change, or do I need to do something to restore them? When I look at the Customize toolbar settings, they are not listed there to add to the toolbar.

I also looked to see if I had a previous profile to load, but it is not showing any.
