I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

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.

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

I want to keep browser open after closing last tab. I changed the boolean parameter "browser. tabs. closeWindowWithLastTab" to "false" but the browser still closes with closing of last tab.

What else is required ?

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.

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 post or write something on my homepage. I then want to share my post to groups I belong to. I hit the share button and get this new and poorly designed response to share. I go to the 'group' share icon. It then lists the groups I'm a member of. So far so good. I then click on one of my groups that I want to share the post with. I get a response, like previously before this new change, allowing to write something to the group along with the post/image I want to share. But there is no 'share' button that allows me to share the post. When this hideous new change came into effect there was a sliver of blue at the bottom, obviously from the share button, and clicking on this allowed me to share my post. Unfortunately, the next day when I attempted to share my post, the blue sliver disappeared and there was no way I could share it to a group. For some reason I cannot take a screenshot of what I'm writing about. Your thoughts?

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

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!

when i amon a webpage& click to go to home screen takes about 10 minutes & i have hi speed inernet & th slide bar on side dont go to top when changing pages getting worse please fix it

Hello, I recently find products added to check out from various sites to purchase. I use all my pcs and other devices. They are all password protected. No one uses my devices. I think some one got my account. I changed the password. Can you help me about this topic Kind regards sami

I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.

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'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.

'bold text'bold text FIREFOX NO LONGER WORKS WHEN YOU CLICK ON THE LEFT ARROW TO MOVE TO ANOTHER ARTICLE. I HAVE PAGES & PAGES BEHIND THE NEW ONE IT ALSO HAS A BLUE LINE UNDERNEATH THE ICON THIS HAPPENED ONCE BEFORE & I FOUND A WAY TO FIX IT, AFTER WELL OVER AN HOUR WORKING ON IT i CAN'T I WANT TO DELETE IT

The file icons on by desktop were always the standard color but now the are blue and white why did this happen. I know I can change each one back individually but how can I change them in mass.
