Firefox 技術支援討論區

I just got a new to me computer and it has Firefox 125.0.3 (64bit) but I was more comfortable with what I had Version 124.0.2 (64 bit). What would be the downside of changing to what I had? I just use it for home use and browsing. How would I go about making that change. I'm not to knowledgeable about computer language and stuff. Thanks, Larry

My Firefox Browser was just upgraded. It seems address bar searches all go through Yahoo.com. Is this by design? Not sure I like the search results...

I'm currently on a very old version of Firefox simply because the new versions, each time I try the latest versions, seem to not have the function the old one has. Remembering the websites I put into the address bar. The version I am currently using did have a issue with shuffling the order of the sites based on 'use' but setting Firefox to Private mode kept the websites locked in order and did not make them shuffle if one was clicked more often than another. Is this something I can do on the current version because I tried and looked for a way to do this recently but I kept getting 'autofill' results from google when I just want to be in Private mode, have the websites I frequent be the only ones listed when I click the address bar and not have them shuffle or have any other website I'd type into the bar not add itself to the list. If this is or isn't possible let me know.

How can I set the default language fir Firefox to English? Currently browsing results always come up in language of my geographic location, for example, Romanian while in Romania. Never had this problem before.

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

I have been using Firefox on my Mac for years with no problems. Recently, however, I have been having trouble running YouTube. I get to the correct page for the video I want but the video itself does not show up, just the background for the page. Any idea what I might have done to create this problem?

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

Every time I sign onto Firefox I get the attached message. I think that uninstalling Firefox and reinstalling "may" resolve the problem, but Firefox won't uninstall. I have tried four different ways and it won't uninstall. Can you help me an uninstall process?

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

I am trying to add custom search engines to Firefox. I have tried the steps given in the forum thread https://support.mozilla.org/en-US/questions/1212596.

However when I try to go and add the search engine as per the article given above I do not get the option. Please see the attached screen shot for more details. I do not want to add an extension or a plugin, but just manually have the option of adding search engines.

When I try to use needed tools on websites, Mozilla is blocking the page from opening. USPS will not allow me to track a package. When I enter the tracking number, the page just sits on white and the search just spins
