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?

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

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:

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

Firefox doesn't respond after attempts to sign on to GMAIL or Amazon (both with passkey option). I have to force quit from Apple Mac main menu. I am using LastPass.

I set up my new tab (after the Home page which was Google News for my profile) to show shortcuts in four rows. Clicking on these shortcuts opened the URL for an account or webpage. I "pinned" or "dismissed' these shortcuts over time. Somehow, I lost every shortcut and cannot seem to figure out how to recreate this.

This setting, "Always ask you where to save files," is definitely broken.

In a related article, they provided this solution: https://support.mozilla.org/en-US/que.../1534384 https://support.mozilla.org/en-US/questions/1534384]

Proposed solution: "I believe you also need to go into Tools -> Settings -> General and set the Action for the types of downloads (Applications) to Always Ask for those types you want it to."

But this workaround should not be needed. "Always ask" means always ask. As in always. No other additional steps should be needed.

Can you folks please open a bug to get this fixed? This used to work just fine in (much) older versions of Firefox and Netscape. "Always ask" is supposed to mean always ask. Like, always.

I have Updates set to "Check for updates but let you choose to install them" - but several times recently Firefox has blocked me from opening new windows with:

"Restart to Keep Using Firefox An update to Firefox started in the background. You'll need to restart to finish the update. Your windows and tabs will be quickly restored, but private ones will not."

Why is Firefox starting to install updates WITHOUT my consent?

And how do I stop Firefox from doing this?
