Firefox supportforum

Even though I have selected Firefox as my default browser, when I click on links in emails or other sources, the actions continue to open in Microsoft Edge. This is a recent phenomena, starting within the past couple of months. I have repeatedly checked my settings, but Firefox always shows as my default browser.What can I do to stop this nuisance? It's a pain to have to copy and paste the web address from Edge to Firefox. Is this an MS hack? Please advise.

I am using Firefox 122.0.1, Windows 11 with all latest updates. Recently my HP Laptop has been slow to respond. I rebooted and opened task manager. I started Firefox and it was using about 1500 MB of memory. I closed some tabs to try to recover some memory. However, Firefox kept taking more, more and more. After 15 minutes, it was at 10,000 MB and climbing, and my system was using 99% of memory. I don't believe Firefox did this in the past and this is clearly not working properly. Any ideas?

Hello; so, my brother lend me his old laptop, clean. I signed in firefox with my account and explore normally. One day, he need it back a couple days so he can work while he repairs his main machine. Log off of my account and log on in his. Now my bookmarks, historial, loggins, etc appear in his session. We think that can not be possible with separate accounts with different associated e-mail and passwords, but here we are.

There is a way to separate my things from his account? It only happens to him, i don't have in my browser his data. Thanks

Hello, my mac ran out of battery. When I restared it, the firefox page restarted, but I can't see it. When I click on it in the app scrolling menu, nothing turns up. It's like it is there, but as a ghost, invisible. When I close down firefox, and restart, it's still exactly the same. I had hundreds of tabs open there, and I don't want to loose that session. When I open a new window, it works, but I can't make the prevous one appear. What is going on, what to do? I'm quite desperate about it, already spent hours looking for solutions.

Hi, I have recently update my Win system with everything including Firefox. And now when I open new tab there is the same Firefox icon like always, but when I it is loading new page then its new X. When it is done with loading it changes to OK icon of the dedicated page. Is this X normal? Thank you

Hi all. I've been experiencing over the past months an increasingly frequent problem where trying to load a web page shows a spinning wheel for as little as 3 minutes but sometimes until you finally lose patience and close it. When this occurs, closing this tab has a 2-3-second delay.

After the problem ceases temporarily, I will be able to load the same page a few times afterward without problem, and it will work for some time until it happens again. I can see no rhyme or reason to it. When it occurs, no pages of any sort will open; I have to use another browser to try to find solutions. When the current recurrence of the problem stops, all pages that were stuck with spinning wheels now resume loading again at the same time. It's like something is breaking internally then resuming some 3-20 minutes later.

This does not occur on any of 3 other browsers (Vivaldi, Yandex, Opera) that I have tried. I have never run into this issue until it started several months ago.

I have gone through the steps shown in the help document for pages not loading on Firefox but loading in other browsers. I have turned off the indicated settings (IPv6, forced HTTPS, no proxy, use only my ISP's DNS, etc.), removed all extensions, and completely reset my profile to defaults.

Just don't know what else to do here. It feels like it's got to be a bug. I do know that I have recently in the last months split into running separate work and personal profiles. It's affecting both profiles, and one of them was created at that time. So also wondering if it could be a problem with having separate Firefox threads/processes running and causing problems with each other, since I constantly have both profiles up separately.

I had Wavve.co app installed on my laptop. Was using it but started to have problems (ie, the app slowing and then not working at all). Firefox showed me a message that said something to the effect that this page was slowing down the browser, did I want to "Stop Page"?

So I clicked "Stop Page", but now even after doing a reset to a date PRIOR to installing the app, I still cannot access the app on this laptop. Will I now need to switch to another browser to continue working with Wavve? Is there ANY way to UNDO that action? Suggestions?

Thanks in advance for your help.

Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

I don't know in which version exactly it happened but a few weeks earlier i was able to edit cookies like we can on all other browsers, but today suddenly i cannot.

I expected it to be a simple double-click and i can edit the cookie key name or value but it doesn't let me edit, it opens the detailed view about that cookie. I looked EVERYWHERE and could NOT find any way to edit the cookies for hours and this is really frustrating as a dev. This is important to troubleshoot many kinds of bugs when I am developing an app.

After updating to the new version of Pocket on my Windows 10 pc, I found that all my previous saves have disappeared- even after switching to Mozilla Firefox browser. How do I get them back? This is a disaster.

Thanks!

Dear Team. As always thanks for a great browser... I had a Firefox update come through this morning (through the browser prompt). After installing the update the pc became extremely sluggish. Thought it may need a restart so restarted the pc but pretty much the same issue? Slow, delayed and sluggish.

I checked what was running in the back ground and other than the usual microsoft nonsense and background stuff it showed 30 instances of Firefox running taking up 82% of the memory. I always have one browser with 8 tabs running by default.

I'm running an i7 processor with 8gig of ram which should be more than ample. Any thoughts / ideas would be most welcome. Once again, thanks for the best browser....

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.
