Firefox 社群討論區

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.

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'm using Firefox 150, but I don't see a VPN button, not even in the extension drop-down menu. There's only a new button for my Firefox account (F). When I click it, I can only choose the paid VPN options.

"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've just opened one simple Web site (in addition to Mozilla), and already CPU usage sits at about 20%! Please refer to my recent posts here at "Why is Firefox Suddenly Taking Over my CPU?" for the problem description. I'm re-posting simply in hopes that I can "send data" on this one from outside my sandbox. Regards -- jclarkw

Hi, I just upgraded from Windows 7 to Windows 10 home. One of the things that has changed is that my downloads don't stay. After closing Firefox the download is there but if you click on it it says "File missing or moved".

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.

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.

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 have noticed that since around Friday, April 24th, 2026, that Youtube videos will sometimes refuse to load properly. The page for the video will come up, but buttons on the page will not load, and nor will the video. This started happening around mid-day, when prior to it, things had been fine. At first I thought it might be tied into the 'ambient mode' option on Youtube itself., But even after shutting that off, I found it was still happening at ranodm.

Is this something new Yotube is doing in their continued (idiotic) fight against ad blockers, or is there an actual glitch in the browser or, more likely, a glitch in Youtube? Like I said, this seems to occur at random and I can't trace the cause for it. I'll include a screenshot of what I'm seeing. But if anyone knows what's happening here, I'd appreciate it.

I should add that I am on Windows 11 and using the new version 150.0 for Firefox. (Congrats on that, by the way.)

I'll be honest, I keep hearing some other browser can block youtube ads innately. (Brave, I think it was called?) and while the idea is cool, I'm not giving up a browser I've used for over 20 years for it. If Firefox can find a way to implement a similar means of blocking Youtube ads innately, I;d love it. But for now, I just wanna know what the devil is happening with the site. Can anyone help?

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.

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