Firefox Community Forum

Hi,

Any suggestions for Firefox being really slow? Slow loading webpages. This has been going on for about a month. Maybe longer. I have the same issue in Troubleshoooting mode. Firefox is updated. Cleared cache and cookies. Rebooted. On a Mac laptop.

I keep using Safari and I'm about to more over permanently.

Thanks!

Heya,

I am the maintainer of the British Dictionary.

For one year that I have been working in the "shadows" on my version of US+Canada+Australian, to be released on 1-JAN-2026.

Can I add your list of proper names (~5000 words) to my dictionaries and release the dictionaries as LGPL?

Thank you!

I've been using Firefox since forever but over the last couple of months, the auto translate subtitles (to English) hasn't been working when watching Youtube videos. There's a thread on the Youtube support site with nearly 40,000 posts of people with the same issue and tonight I was trying to watch a video where the hosts talk in Italian, so I use auto translate to English subtitles but no subtitles appear. It will show Italian language subtitles.

I've gone back through this Youtube channel's history trying videos I've previously watched from months/years ago when auto translate used to work but even they're not working now.

I decided to try the video in Edge browser and to my surprise the auto translate to English worked there. They also work in Chrome.

So what could be causing this issue on Firefox, which started about August time?

This is quite bizarre as I assumed all the processing/translation was done by Google/Youtube so in what way can Firefox be part of this issue?

To be clear, subtitles in the (foreign) language the people are speaking, works. Subtitles translated from that language to English (or other languages) has stopped working. Subtitles translated from that language to English IS working on Edge and Chrome browser.

I have an old Laptop which works perfectly for what I need, and I use Firefox for my Browser.

I had to shutdown my Laptop and everything seemed Ok on reboot. However, I can no longer access my Gmail account as I apparently "need Chrome" to get access...?

Do I? If so - how do I get it installed on my system?

Thank you

When I access a specific website the .css files hosted at http://cdn.ct-static.com/ don't load. The Network Tool console indicates that they time out. I have been told this is usually a network setup issue however if I use the MS edge browser the site loads. How do I troubleshoot this?

Yes, I'd like to use the same account on both of my profiles.

I understand that for some users, this may be confusing.

In my case, the only reason for different profiles is that I need to use a Proxy Server for some websites, and no proxy for other websites. Manually switching proxy settings is painful, and doing so causes traffic for my other tabs/windows to go to the proxy, which I do not want.

I have a main (set of) windows (and its tabs) going straight to the internet, then I have a separate window (and its tabs) configured to go through a proxy (SOCKS5 in this case). I want all other settings, bookmarks, passwords, etc. to be identical to both. I end up having to logout of my main profile, log into the other profile to sync settings, log out of there, and log back into my main profile.

Is there a valid technical reason why an account on the same FireFox installation cannot be shared between two profiles?

I can do this on multiple computers (same account, different computers/profile), seems odd it is restricted to not allow on the same computer.

I have an alternative solution: Install FireFox natively, then install FireFox as AUR or FlatPak, but not sure this will collide as this both uses the same profile directory. Hum...

I'm trying to use an old Apple Powerbook as my 2015 MacBook Pro just died. I use Firefox as my browser on my PowerBook, and it is asking me to enter my old phone number and is not accepting my new phone number.

Using Firefox 145.0.2, Flatpak installed via Bazzite's Bazaar store, there is no "sparkle" button in the sidebar, no options present like there are when I use Firefox on Windows.

I haven't been able to find a keyboard shortcut for switching between FF windows. I'm using MacOS Tahoe. Is this in development, or is it there and I just haven't been able to find it.

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

By addressing the problem that I have typed above. Why for over a year have I been getting 'Firefox not responding' message? I then have to start again every time. Thanks

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files
