Firefox Community Forum

Hey, I recently started using the Firefox browser, and I have a lot of websites. Sometimes I manage my websites on firefox for the last 1, 2 weeks, whenever I open my website https://manatoki.click/, it sometimes shows a 404 error: site doesn't exist.

It doesn't happen every time but sometimes this issue comes. Then if I open the website again in a new tab, it opens fine. This only happens with Firefox for me. Why is this happening? Is it a host or server connectivity issue, or should I just ignore it?

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'm getting the following error message:

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.

I don't know what prompted this concern on my Windows 11-based laptop, but I only noticed this last night doing some research for another issue. I don't have any of my bookmarks showing up in the bookmarks section, nor will it allow me to click the star on any tab to bookmark the page. I have restarted and shut down my laptop several times and this is not solving the concern. Let me know if you need more information or if I need to start this inquiry again elsewhere, but again it sounds like the same concern.

I have included a screenshot of the exact error for accuracy's sake. Like everyone else here, I'm trying to get my bookmark and history access back up and running but not sure how to go about it.

I couldn't get past the first fix suggestion because I am not sure how to restart Firefox (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US). I have restarted my laptop several times but the issue still persists.

Please advise.

Ironically, I am not having this issue on my older PC that is still operating on Windows 10. I can view history and access or add bookmarks with no concern to my knowledge.

I have a new MacBook Pro M5, with MacOS Tahoe Version 26.5.2, and currently running Firefox 153.0. Over the past few days, I've noticed that the Fn-Delete (forward delete) is not working in the file name field when downloading a file from the internet. Fn-Delete is working everywhere else.

I'm not certain if this started when I set up the new computer, updated the MacOS or updated Firefox. I'm pretty sure all have occurred within the past couple weeks.

Thanks.

I go to yahoo and have internet connection. When I go to yahoo mail and click on an email a box comes up saying "No Internet connection". I can go back to yahoo's home page and everything works fine. I tried Safari to see if I had the same problem and if it was yahoo mail. Safari worked fine. Why is Firefox not connecting to the Internet in Yahoo mail?

The VIEW tab in my Firefox will/can read some links and articles to me. It is wonderful.Choosing 'READER VIEW' in the VIEW tab. But some it does not. I'm hoping some AI will have this feature.- speaking it to me. Thanks.

Pop up notification for an outdated profile/version of firefox when firefox was closed which made the game tab out and I couldn't move until I was able to tab back in. How do I get rid of this and keep my current profile and get it up to date so that I can use the same profile?

I’ve had the Firefox app on my iPhone 15 and have used it many times as the search engine. I noticed now when I try to use it as a search engine it seems to be hijacked by DuckDuckGo as that is the search engine. Past searches would give me a Shortcuts to where I wanted to go but now all that’s gone. Trying to download it again it will not download
