How to put Firefox on a diet?

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I use Free Download Manager v3.97 along with FF Free Download Manager extension v3.22 to download files from Easynews.com. This issue may have nothing to do with Firefox except that the problem started a couple of days ago about the time 1.46.0 was installed.

When I right-click to download a video file, FDM is configure to automatically start the download. But downloads are not starting automatically now. FDM just shows the download with an hour glass figure. I have to manually stop then start the download.

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

Since the last update, Gmail has not been working correctly on Firefox. All of the buttons to the left of inbox emails that enable you to move, categorize, file, etc your emails have disappeared. I have tested my Gmail account on Chrome, Edge and DuckDuckGo browsers, and everything displays correctly. Please help. An image of the missing buttons is attached (well, since there aren't there, you're seeing a blank area of gray to the immediate left of my inbox [or any other folder] emails). Many thanks -- this is driving me crazy. P Haynes

Hi. I've downloaded dictionaries and languages, the check spelling option is enabled in the browser settings. However, browser doesn't want to do it automatically. I have to manually enable it with RMB context menu (and re-select languages) for each website individually. Moreover, when the page refreshes, spell checking turning itself off again in RMB menu (but stays enabled in browser options).

  Is this really how it's supposed to work?

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

  • I have verified that the browser itself is technically updated (via Help > About Firefox).
  • The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
  • This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

I can't find a place to manage my payment methods. The only place I found that was when I check out and fill in my information in a store website.

The browser suggests my card and under that it says "Manage payment methods".

When I click that it opens "about:preferences#privacy-form-autofill" and then quickly becomes "about:preferences#privacy".
