Javascript is not working in my firefox. Even going into settings to enable java script doesn't work, because it says java script is enabled. But the webpages tell me that they need javascript enabled in order to work.

My primary google account's language is set to english. If I search normally, then the results are shown in english. If I open a private window and search in google, the results will try to be in the regional english and google asks if I want to switch to english every time.

A week ago I got a BSOD that ruined settings of most of my extensions and most likely some of Firefox's settings too (at least it erased my custom findbar.matchdiacritics value, but probably not just that). After that I moved Firefox's folder and re-installed it. I also created a new profile. The 2 profiles are synced. Because of that, the new profile got (almost) all the extensions from the old one automatically. Then, I decided to do a clean install of those extensions (the reason why is a story for another ticket). So, while both profiles were opened, I removed one extension in the new profile, waited for a bit and checked the old one to see if it got removed from there too. At first it wasn't, so I thought they are not synced (anymore). Yeah, sure, but once I removed all extensions from the new one, the old one woke up and removed all extensions from there too. Great! Awesome! Loved it wholeheartedly! It really had to wait until I removed them all, didn't it? Anyway, I had a backup of my old profile, so I restored my extensions and their settings on both profiles eventually. So now I have clean installs of Firefox and extensions. Back to the issue. I can't load Steam pages (at least store.steampowered and steamcommunity) normally anymore. They load forever, and if the blue dot eventually stops moving (after an insane amount of time), it's either a plain white screen, or badly loaded page with most images missing.

• Edge loads them just fine
• Steam client loads them just fine.
• If I turn on VPN plugin (I use Browsec), then it works. It's like that in both old and new profile. That's why I mentioned that funny little story before.
• Tried Troubleshoot Mode, didn't help.
• Tried to selectively disable some extensions, same.
• Obviously tried to remove cookies, Ctrl + F5 and whatnot. Btw, if I clean everything and try to load it, then it's (most likely?) a white page, but if I turn the VPN on and load it first, and then turn it off and reload it, then it will look a bit better, but still will load forever with some media missing. (Which kinda make sense since something was already cached.)
• Tried to change proxy settings from “Use system proxy settings” to “No proxy” and “Auto-detect proxy settings for this network”, nah-ah.
• Tried to disable DNS in Firefox's settings, no siree.
• The console throws different warning and errors every time (that are probably even unrelated). Or none at all.
• Probably tried something I already forgot about.

Also, it seems the culprit is actually Akamai (it's where the Steam stores its media) or whatever is preventing reaching it. Because it often shows something like “Waiting for community.akamai.steamstatic.com...” in the status bar for a long time. It seems like the problem is within Firefox's settings, and it also looks like settings aren't synced across profiles (or at least some aren't, I definitely had to configure them on the new profile manually). Anyway, I am out of ideas and my butthurt thrust is about to deliver me to Uranus. Thanks for your attention!

Best regards,

At the beginning of 2025, I created a private theme and installed it locally (Windows 10), consisting of a manifest.json and a GIF file. It worked perfectly. Now, on Windows 11, I'm trying to use the theme again, but when I upload the file (.zip or .xpi — via about:addons -> Install Add-on From File), I always get the message that the file is corrupted. However, if I test it temporarily under about:debugging, it works immediately without any issues.

I would really appreciate a solution! <3

When trying to print something using Firefox it automatically wants to print 2 copies, despite refreshing, rebooting, reinstalling and checking browser settings. This issue does not occur with other web browsers such as Microsoft Edge.

Hello All -

Over the years I have saved many bookmarks across several different devices. Therefore the bookmarks vary between devices. Is there any way that I can tidy up my bookmarks, deleting many of them, on my main machine and then have all the other devices Synch to that list only?

I have tried deleting ALL the bookmarks on the "subsidiary" devices and then synched them but that didn't work. I think I'm asking whether one device can be made the "master" for all the others to Synch to that one and none of the others.

Hope that's reasonably clear.

Thanks,

Ian.

I saw bunch of threads which suggest to enable "ctrl+tab cycles through tabs in recently used order". It does what I need, but in previous versions I used to press only ctrl+tab. While I was holding ctrl I could iterate over tabs via tab key. After releasing ctrl selected tab was chosen

It differs with current behavior where you press ctrl+tab and after releasing all keys pop up with tabs is still be viewed and you need manual action with space/enter/mouse click to open selected tab

Is there any way to use only ctrl+tab without any manual actions required like it was back in the days where after releasing the control key selected tab is opened?

Why am I getting this message: with no way around it?

I downloaded an extension and can't do anything with it. There is no way for me to open it, all I can do is open up my extensions to see it then change permissions or delete it. It won't appear on my toolbar with other extensions. I've seen others ask this question and the solutions dont apply to me. People are being told to either right click and click pin to toolbar or to click the gear icon next to the extension and then pin to toolbar as well. I have no gear icon next to extensions and right clicking an extension treats it like a link. There is a gear at the top that when I click it I can click "manage extension shortcuts" only for it to then pretend none of my extensions have shortcuts even though 2 of them are right there in my toolbar. The 3rd 1 mozilla seem to not want me to have on my toolbar.
