Best Buy Tech support took control of my computer today to get my printer to scan to the computer. After that was done, I went to my FIREFOX hompage only to see it completely changed from the way it was and I am now trying to get it back.

"I’ve been having trouble with choppy YouTube videos in Firefox. It happens on both Wi-Fi and Ethernet connections. My system is running Windows 10, and I’ve already tried disabling hardware acceleration and clearing my browser cache. The issue persists even when I’m in Safe Mode. I’m using the latest version of Firefox (XX.XX). Any suggestions on how to fix this?"

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!!!

When I click on the search box in the middle of the New Tab page and start typing, the focus automatically jumps to the Address Bar (Awesomebar). I want the typing to stay within the central search field.

In about:config, I have set browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false. However, this did not fix the problem — the input is still being redirected to the top address bar.

All of a sudden, my default search engine changed to Google. I didn't do it and don't want it. The "settings" still show Firefox as my default, but it doesn't stop Google from hijacking my searches. I want to get rid of it.

The latest version of Firefox appears to have updated a setting: When selecting a custom search engine in the address bar or search box, you now need to click the mouse three times (click the dropdown button on the left side of the box - select search engine - search); previously, after entering search terms in the search box, you only needed to move the mouse icon below the box to automatically display all search engines, and then click the desired engine to search directly, thus completing the search with just one click.

The old setting was very convenient; while the new setting forces me to click several times every time I want to search for a term in the search bar.

I hope the support team will address and improve this issue.

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

always I use virustotal for cheching safely of any URL. this morning , FF149, does not work, error message "403 Forbidden"

is this something new from Firefox, just updated to 149. or is there a problem with virustotal?

Just as the summary says, Used to have an icon that I put under the "hamburger" menu on the bookmarks toolbar that opened the bookmarks menu. Can't remember how I got it there. Can someone help me get it back.

To Firefox engineers and volunteers:

I am a native speaker of simplified Chinese, and I am currently running Firefox 149.0 for Windows desktop. There are some troubling issues and I hope to be able to fix them in the next version. Thank you very much.

The problem I encountered was that at least eight options, all in English, appeared in the browser's privacy and security settings, this has been in Simplified Chinese in previous versions of Firefox.

As a simplified Chinese user and English level of the user, I feel very inconvenient when using, I hope to get your response, thank you!

The original is simplified Chinese, I use the translator to translate into English, if there are mistakes please forgive me.

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.

Desktop Firefox 147.0.3 (64-bit) When I open Facebook, pictures of accounts are continually blinking (not flickering). This problem is new and appeared just after last Firfeox update.

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

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.

Firefox stores certain temporary data in a startup cache to improve startup speed. Clearing the startup cache and then restarting Firefox can sometimes fix various issues, such as mixed languages in the user interface after an update. This will not change your profile data or add-ons.

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.
