Firefox Support Forum

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

I switched to Firefox DE because I wasn't able to install 3rd party extensions. Just now, my middle click isn't working. I can't use the middle click to open/close tabs and to open links in a new tab. I checked my settings, tried a new profile, nothing works except in normal Firefox, the middle mouse does work, but I don't want to switch to that. My middle click also works in Edge and other apps, but please fix this issue as soon as possible. Thank you.

PS. Please add biometrics to Firefox, like how Google did with Chrome.

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

I'm on Firefox Developer Edition 119.0b9 (32-bit) and Windows 11 Pro 22H2 but I've been experiencing this problem a lot longer ago even before upgrading to Windows 11. The first thing I open in my computer is Firefox, it gets the window itself quickly but the page stays blank with the gray loading dot going right and left for nearly 10 minutes before the page loads and Firefox works normally. I don't experience any issues while browsing the internet after that long loading but it's really annoying especially when I'm in a hurry and I don't have 10 minutes to stare at a blank page.

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.

My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

I'm having an issue that seems to Lock up YouTube on Firefox.

I'm trying to get back into using Firefox but I'm having a persistent issue in both FF Mainline and even in FF Beta 119.

If i play a Video on YT then switch tab to do something else then go back to YT it lock up the video window. I do not have this happen on Chrome or Edge.

I have tried refreshing the browser and still have this issue.

I'm new to Firefox, usually in other browser, like Chrome and Edge, when I use the selector to choose element and click on it, it will bring back the console but it doesn't seems to happen in Firefox. ( I'm using separate window for the console )

On some sites like youtube, crunchryroll, and other sites usually where it's main purpose is to play videos my sound plays fine. However, on other sites like osu's website, chess.com, duolingo, and others, there's no sound at all. I've tried refreshing, restarting, running in safe mode, and even reinstalling the browser but none of it has worked. My tabs are also not muted. Does anyone know how to fix this?

Hi all, I've got a puzzling problem with just one desktop PC on my network, and only in Windows 11 (fully updated) - the same PC when booted into another OS (Ubuntu) works without any issues.

I have a fresh install of the latest Firefox as well as the Developers Edition. MS Edge is also updated to the latest build, yet none of them can load the "accounts.firefox.com" page.

All I get is a completely blank page, save for a blue circle on the top left corner. I've tried all the usual resetting, Troubleshooting Mode... etc, (issue is present in Troubleshooting Mode) and pretty much stumped at this point.

All other websites I've tested with all browsers don't seem to have any issues at all, including the likes of "accounts.microsoft.com" or "accounts.google.com".

Google hasn't turned up with any results matching exactly what I'm seeing with this particular machine/problem... hoping someone can help pointing me in the right direction.

Thanks in advance,

hi!, so i downloaded a couple videos on mozilla, i saw them in my downloads but i didn't open them, now i delete them from mozilla and they were automatically deleted from dowloads and i can't find them in my recycle bin either.Is there a way to get them back?

Latest version install (116) causing functionality issues in Google apps, and other Windows 10 apps. Tried to install an earlier version and that did not work. Tried the Beta version (Current 117) and no changes.

I am developing a website (using AstroJS, but i don't think that's the problem) and since yesterday I am experiencing issues when opening devtools. Once I open devtools the whole FF tab becomes unresponsive, I cannot even refresh the page until they are done loading. I can change devtool tabs from 'inspector' to 'console' to 'network' etc but especially 'network' and 'debug' tabs are blank.

I run a 'performance' capture and got these results. In the test I have only opened the devtools and switched to the inspector tab which is unresponsive. The CPU usage is at around 90% however, I don't really know how to read the finding and understand what the problem is.

So anyone that can help me understand what is going on here?

I'm getting loads of SSL errors when trying to connect to various web pages. The errors don't seem to relate to the target pages, something in the connections fails.

The symtoms appear to be similar to this closed bug which doesn't seem to have been resolved. https://support.mozilla.org/en-US/questions/1378352

Two of the more recent errors were: SSL_ERROR_DECODE_ERROR_ALERT SSL_ERROR_BAD_MAC_READ

There were several more which I don't remember.

Has anyone come up with a resolution?

Hello,

Why when I drag & drop files to Outlook only URL is pasted instead of file? Is it possible to change this behavior? In Opera browser it works fine. Example in attachment.
