Firefox Community Forum

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.

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!

I've tryed all obvious instructions and my bookmarks toolbar will not sync

Hello,

I have disabled AI according to the instructions given by Mozilla, under settings and AI controls. When I search, I still get the first result as an AI generated result. I want to disable that. I don't need AI's help to understand what I am looking for. I want an old school search without AI.

Is this possible? If not, could you please make it possible?

Thanks.

I cannot sign in to my banking website. I assume it's something to do with cookies or permissions. This is on my desktop, but I have no problem on my I-pad. I have the latest version of Firefox and I am using Windows 10.

Hi, Firefox (PC or Mobile) can't load this web page ( https://www.keter.com/fr-fr/nous-contacter.html ), but Google Chrome or Microsfoft Edge can. Screenshot with Firefox and Chrome Just this form, i can browse the site without any problems. Any ideas? Thank you

when i right click my search bar on the top of the page i cant find the button to delete my search history anymore when it was there like yesterday. is my computer breaking or something??? help

When I've had trouble signing-in to a commercial website, it often says, "Clear your cache." But in Firefox settings, it looks like clearing it will cause my frequently-used passwords to disappear. Am I reading that correctly? If it's true, how can I clear my cache without losing "remembered" passwords and other log-in information?

I'm not very tech-savvy, so need instructions in very plain, "for dummies" English. Thank you for any help.

Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

You say to go to the download page and my version of Windows will be detected & you'll give me the correct version. However, IE 8 in Windows 7 won't go to your download page. So, I need to download from another computer and copy the file to the Windows 7 computer. This doesn't work when you detect that the computer doing the download is a newer computer. How do I tell your system to give me the Windows 7 installer?

Firefox detected a potential security threat and did not continue to apps.ngte-welfaretrust.gov.bd because this website requires a secure connection.

What can you do about it?

apps.ngte-welfaretrust.gov.bd has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

I dislike having my search suggestions show in the address bar. I have cleared the box on the search settings box, however searches continue to show only in the address bar. If i go to the Google home page the searches show on a webpage Any help will be appreciated.

I have had so much trouble w/ FireFox VPN. At this point I'm convinced Google is paying the CEO and crash Mozilla straight into the ground. I paid for annual sub, then like something changed (they couldn't honor one of the services (email relay maybe?)) and then I had VPN for a bit and then all of a sudden it got cancelled. Now I have it turned on after they took a while to get back to me about asking why it was turned off (I guess at least they got back to me eventually), but when I go to check my account info about when my renewal is becuase I'm highly thinking about going over to DuckDuckGo and WaterFox, I click on "Paid subscriptions" options and get a refresh of the page w/ a "failed to load page, contact support" every single time. Then when I follow link to "contact support" I get a community forum option, It's giving BROKE!! I really have loved FireFox for so long but I'm thinking this might be the end. I even tried working for Mozilla, but decided not to due to the Five stage interview process, which clearly is not working out for them. Were they really able to screen the best of the best developers with that type of interview process? I digress...
