Hello I have reinstalled my firefox on a new reinstall of windows 10 as my older version 10 crashed and went to the wall. however I have all my tabs and fafourites up and running but when i try and download my paid version of Nord VPN firefox comes back and says its not secure and wont load the website ? this has been working for me in the past. any advise would be greatfully accepted. thank you.

I've been using Firefox and Gmail on my PC and android phone for years. Today I can't log into my gmail account on my PC and instead it redirects to google support and goes on about clearing cache etc etc. I have cleared the cache but no different. I have restarted my pc and no different. PC is Windows 10.

I can log in to gmail using Google Chrome so I can't see that it is a Google problem. I can also log in ok on my Android phone.

Is this a Firefox issue?

I've uninstalled Firefox and reinstalled it and cleared the cache. And it's still either not linking to certain sites at all or not, opening them correctly or completely. I don't wanna spend any more time than necessary on this since i've tried various ways to fix the issue.. If you can help me, that would be great. I guess I could use chrome, but I have used firefox for years.And as a rule, haven't had any problems up until now.

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"

please forgive me for asking again, but I REALLY need my addons to work. Firefox disabled my addons, forcing me to upgrade to a version of firefox that I don't need, since the old one was working just fine. The new version does not seem to appear to have downloaded properly, and neither version is allowing my addons to work or be re-installed. Please explain it to me like I am 5 years old, and help me to get this fixed without losing any of my info that might be stored in the addons.

 Thank you.

Hello!

A very important email folder in my Thunderbird just vanished. I didn't touch anything! My email was downloading very slowly and so I closed the entire Thunderbird application. When I re-opened it, the folder was gone. Everything else is there as before - all other folders, my inbox etc.

I have no idea what happened or where the folder went. I can't find anything online that addresses the problem or how to solve it. I'm very much a tech novice. I need a solution that a 5 year old could navigate lol

System: Linux/Fedora41 Firefox: 136.0.4 Monitor: Acer 27" 1920x1080

When I open a FF window, it opens full screen vertically and to some width horizontally, both dimensions not desired. My usual style (for the MANY years I have used FF and Linux) is to use a FF window that is NOT full screen in either dimension since I normally have multiple windows open simultaneously. This FF behavior has started just recently.

This behavior occurs when starting FF from the FF icon on the desktop, when opening a new window from the FF main menu, or when opening a new window via the 'Open Link in New Window". (Perhaps other ways as well: these are those I encountered.)

I have tried: .... Opening FF/resize window to desired size/close FF using 'Quit': no change on restart .... Deleting the xulstore.json in the profile folder/restarting FF: no change on restart

I would like to restore FF to its previous action: open new windows at the same size as the last one referenced. Can someone help?

Thanks.

Firefox recently sent out its monthly newsletter (Oct '25) with all sorts of options that can be enabled on Firefox. I'm a computer illiterate & foolishly chose some of the options -- don't remember which nor know how to discover them.

Now javascript is no longer enabled on my MacBook Air (macOs Big Sur 11.7.10). I cannot access my protonmail account and many many other sites.

I've gone cross-eyed accessing "fixes" that are labelled "only for advanced users" & am bright enough to not even try.

Is there a simple fix (short of wiping my computer -- with data going back 11 years) that even I can do?

If you have "fixing your firefox for Dummies" then please email me with a solution. [edited email from public community support forum]

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.

Opening again just goes to a reduced size page.

I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.

Still the same problem.

I think there is a file that controls this that is corrupted.

Need help.

Near Firefox. Why does Firefox's built-in translator always write “Near” in front of all opening sentences? It's very annoying to look at. Have you considered using AI? DeepL is great for translating. It translates not only the words, but also the culture.

Why is there a setting that doesn't do [expletive]? Picture-in-picture can't be disabled through settings or about:config..... So how the living [expletive] do I disable [expletive] buggy [expletive]? And how the [expletive] do I set it to continue playing even after closing the small picture? Why is there no [expletive] setting for this while you have a setting that doesn't do [expletive]?

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?
