Firefox Community Forum

Whenever I search for something on Modzilla Fire Fox Browser, I get All the Search results in Spanish. Unfortunately, I don't Read, Write nor Speak Spanish at all. In addition, I have to have it Translate everything into English. How can I change this, to come up in English only, and Not Spanish, whenever I am searching something in Modzilla Fire Fox Browser. Again, I do Not read, write nor speak Spanish (None). This is very frustrating and annoying to say the least. Please advise soonest. Thanks TmKraft

Hi everyone,

I’ve been using Firefox as my primary browser and overall it works great, but I’ve noticed a slowdown pattern during longer sessions and wanted to compare notes with the community.

After running the browser for several hours with many tabs open, I sometimes see delayed responses when switching tabs, typing in text fields, or opening menus. Nothing crashes, but the interface feels heavier until I restart the browser. Once restarted, performance goes back to normal.

I’ve already tried reviewing extensions, disabling a few that I don’t use often, and checking memory usage in about:performance. The numbers go up as expected with more tabs, but I’m not sure how to judge what is considered normal versus problematic.

Because the issue improves after restart, I’m wondering whether this is typical resource buildup, session handling, or something specific I should be tuning.

How do experienced users usually approach diagnosing gradual slowdowns like this? Are there particular indicators in the built-in tools that suggest a real problem rather than expected behavior?

While reading more about how browsers manage memory over time, I found this general explanation helpful for understanding the bigger picture:

I'm having problems getting Firefox to work in Protonmail un able to send emails ...Copy& Paste......I think it is this New Version.............When I removed it from my applications & downloaded Google Chrome it all worked, that tells me the problem is with Fire Fox version I think

Every few weeks I get this error and my bookmarks and passwords are corrupted. I have uninstalled and reinstalled Firefox, per the full uninstall instructions, including deleting old Firefox folders and it works for awhile and then returns.

Error: Platform version '147.0.3' is not compatible with minVersion › = 147.0.2 maxVersion < = 147.0.2 Maybe try to reinstall Firefox?

Hello, If I had to sign into my gmail account in order to download Firefox browser, does that mean that my new tablet (that did not have my gmail identity on it before) is now fully enmeshed with the Google identity, even though I will not use it on this new tablet?

Usually there would be some shortcuts when I open new tab page. But they were gone on the new page from yesterday. Of course I didn't change setting and didn't install any add-ons. I disabled all add-ons. But problem not solved.

I checked 'preferences-home-Firefox home contents', but I cannot see any options(that area is just empty).

I also checked 'about:config' :

• browser.newtabpage.enabled → true
• browser.newtabpage.activity-stream.feeds.section.topstories → true
• browser.newtabpage.activity-stream.showSearch → true

And I compared between 'about:newtab' and 'about:blank'. I found something that background color of new page are different. There are some HTML code in 'about:newtab' when I use F12. But I don't know what is wrong with this.

Firefox won't allow other websites to correct my spelling. This is a big deal and I will have to go back to safari if there isn't a fix. I am using a new computer and new firefox download. Can u help?

I am hoping that a permanent fix can be made to the bookmarks toolbar issue where another program may be using a file that allows it to show at the top of my screen. It keeps disappearing and I complete a fix and it disappears later in the week. Thanks Brian

Firefox 147.0.2 (64-bit) on my Lenovo Yoga 7 Windows 11 Home has been randomly malfunctioning when i use the hover over tabs with the mouse to show what is in the tab (small image) Sometimes it just fails for several hours, other times it works fine on its own later that same day.

I have tried to find this inside the browser several times with trying to find this browser-tabs-card-Preview-enabled inside about:config But it doesn't seem to exist in this version and apparently you can't add a new rule inside the browser to solve it.

Google AI solutions search is outdated or the wrong version. My computer and browser are up to date. How do i fix this ? I don't want to uninstall it, lose my logins and the bookmarks if i am unable to sync my files after trying to reinstall the browser only to find out it has failed.

Been using Firefox since 2014 and as my primary browser for personal research, etc. and Google's Chrome about half the time for company-related work. It's been my favorite browser. I'm using the current updated Firefox 147.0.3 (aarch64) and and Apple's O/S macOS Sequoia Version 15.7.3.

However, for at least 8 months or more now, Firefox has become completely unreliable for downloading files to save on my virtual drive in my MacBook Pro M3 Max because it often if not always freezes up in the process. I have to curse again (!) then Force Quit, reboot, and everything instantly comes back up on the monitor as if nothing happened, only of course I did not accomplish the task of downloading and saving the file I needed to handle.

I have discovered by talking to folks and by researching Firefox's support information library that I'm "not alone".  Not by far.  This problem IS a Firefox issue.  I've tried to follow Firefox's several different solutions to overcome whatever the root cause of the problem is, but without success.  The TIME required to really go through this problem-solving process is a killer.  And, yea, since I'm physically practically in OPEN AI's backyard, I have consulted CHAT GPT and it also confirmed this issue between Firefox and Apple's O'S macOS Sequoia Version 15.7.3 and practically gave me a Masters thesis about.  Who has time for this?  Why can't Firefox solve this problem to make this easy for us?

S0 now, before I update my O/S to macOS Tahoe 26.3, does anyone know if between Apple and Firefox this problem has been solved? For 10 years it was never a problem. What the heck happened? Firefox is no longer my primary browser, for I never know for sure whether or not I'll need to download and save to my Mac's virtual drive a file.

Thanks for any constructive comments anyone may make! And Happy Friday. ~ GPB

Please fix for me this error
