Firefox Community Forum

I have used firefox for 13 years now and I have never had any major issues with it. but recently I have noticed that whenever I open it on my laptop, the laptop freezes and then a black screen, then a mozzila firefox crash dialog box. sometimes I am forced to hard restart the laptop then use another browser. I still want to continue using Firefox but that issue is really frustrating.

Thank you

When I open my website, pvamarkets.com, I see a Cloudflare page that says:

“Suspected Malware — This website has been reported for potentially distributing malware.”

This is a legitimate e-commerce website. After the warning appeared, we completed a full server-side security check. We checked the website files, database, cron jobs, access logs, error logs, and file-delivery system. We did not find malware, executable files, unauthorized code, or signs of a server compromise.

Our website only delivers plain text files to customers. It does not host or distribute Windows executable files.

I understand that the warning page is branded by Cloudflare, but I am posting here to confirm the following:

Is this warning generated or influenced by Firefox or Mozilla Safe Browsing? Can Firefox cache an old security warning after Cloudflare removes it? Is there any Firefox security report or blocklist entry for this domain? What steps should a website owner take to confirm that Firefox does not classify the domain as malicious?

The warning appears before visitors can access the website and causes serious trust and access problems.

I have attached a screenshot of the warning page.

you have to delete over 5 times to get history and cookies to clear. Selecting "everything" never removes everything :( Used to be the best for privacy now its seemingly deceptive..

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.

The mouse cursor does not highlight text in the address bar. It is selecting the text but the blue 'select' highlight doesn't show so I'm working blind. Firefox 154.0b5 Build ID: 20260731090442 (64-bit) on Windows 11 Home 25H2. Build 26200.8875 Tested in troubleshoot mode - same issue.

No point adding screenshots to show an invisible select highlight.  :-)

Name Firefox Version 154.0b5 Build ID 20260731090442

I'm not sure what update it was but, new system so I had to go into setting and set things how I like. I cant remove options from additional search engines in settings. This used to be a normal feature. It is no longer one. I want to know how to remove them. Not just disable them, it is not the same. It's fine, If I have to manually recompile the browser to get this done. I just don't want them there. On version 155.0a1 on Arch Linux.

Any constructive help would be greatly appreciated.

I have just download firefox, but I can't browse any web on firefox. Then, I tried firefox ESR, it doesn't work eather. Only setting page can be open. Microsoft Edge can work well (image 1 left is Edge), and my internat is OK, only Windows Defender work.

When trying to sign up and choosing "English", the page responded: "Select a valid choice. en is not one of the available choices." Isn't that ridiculous? Even so, you knew it's "en" after getting the choice as "English" and still refuses to let me in? I can't believe Firefox can do this! The attached image says it all!
