Firefox Community Forum

I have no issue with youtube on any other browser, but I do prefer Firefox. However, Fierfox says that site is slowing down firefox and suggests I close that page. Firefox did not do this in the past. Is this similar to the rather ugly color of the private window that I can't change, not being a coder? The impression I get is that Mozilla is making changes without assuring they work properly. I currently have to use chrome to make sure youtube works correctly.

I use LastPass to store lengthy passwords and auto open websites. After the latest Firefox update (148) when I click to open a website, the entire LastPass vault page just flickers and returns to the same vault page.

I am just an average end user and want to alert you to my problems and would love a solution. I am sorry that I don't have the kind of specificity in the details which might help (I am too busy doing other things and when firefox becomes too much of a pain, I generally close it and switch to another browser). I am providing my general observations. On my updated windows 10 64 bit system, firefox v148 seems to have made the browser unusable for me. Other browsers do not suffer similarly (Chrome, Edge, Opera, duckduckgo). I have had these types of issues with Firefox in the past, but they resolved with prior updates. I am at the point of switching to another browser - I hate the thought of it, but Chrome seems to be the most stable and functional. Symptoms:

• Firefox browser and the computer gradually become slower as firefox starts hogging cpu and memory and starts using a lot of power
• extensions stop working - eg, Keeper extension stops filling fields or fills incorrectly, Malwarebytes extension seems less responsive, running background sounds makes things even worse (https://www.mynoise.net/) and web pages with continuous updates (eg, map.purpleair.com) stop working altogether
• other pages stop loading, load with errors ('bad connection') or load very slowly, especially, but not always, those with more security, eg, my bank or retirement funds sites.
• after i close Firefox and start fresh, symptoms resolve, then rinse and repeat.

The previous version worked great and seemed to solve similar issues I have had with earlier releases. I assume the last stable release for me was one of the 147 versions. but when things are going well (which is most of the time), I'm not watching closely, or at all.

I use Stockhouse.com as a homepage and when I opened my computer this a.m. the site came up and it asked me to sign in which it normally does these days and I click on sign in and it shows my email and password and I click again and I'm signed in. This morning it asked me to provide my email address and password i.e. fill in the blanks. It has not done that for at least 15 - 20 years. Not remembering offhand what my password was I clicked on the 3 line application tab in the top right hand of my screen and brought up the list which includes "Passwords". I clicked on the password file and it is blank. It has never been blank before -- did Mozilla/Firefox make a change that would make my password file disappear?

I have recently started getting the message "Gah Your tab just crashed" when using firefox W11 lenovo laptop Up to date with updates Started yesterday (26/2) Happens most of the time now Seem OK on another laptop

Going to enter payment method on website and the auto filled credit cards queue up, when a card is sellected and clicked it will not fill in on the website. They area but will not load on the website

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

Hi Guys,

I have an issue. I noticed now that if i click on one of my 300 tabs of website tabs, it automatically goes to some domain reseller and removes the whole link / information on the link that shows which tag or data i had on that link in the tab. If that makes any sense?

I hadnt yet gone through renaming all the tabs when the website changed domainbs and now i am unable to as the minute the tab wakes up from beind discarded, instead of coming up as can not find website (at which point in the past i could just change the 2 characters to the right domain), it goes to the domain reseller and removes the whole link / data that it used to point to.

Anyone know of a way i can do change the links on a mass scale of all the tabs i have?

I am seeing pop up ads like these on the lower right corner of my screen since I updated to windows 11. I've never seen this with windows 10. Microsoft is telling me these are coming through my browser. These are not when I am in a web site and get the pop up to allow notifications, I always say no. These come @ 1 per week or less and I don't seem to be able to stop them. Is there a setting in firefox that will stop them or is this a microsoft issue? thanks brian

The interface is terrible, it makes me completely unwilling to use the browser. Why make the tabs merge without any separation????!! It's disgusting!!

How can I change the tabs' appearance so they appear as individual tiles instead of a continuous view?

The site froze while playing a video. It happened multiple times. Is anyone else reporting this kind of behavior on Instagram. I closed the tab, but cpu stress-like side effects remained for a while.

Initually I was having issues where I couldn't get the print menu to load up (forever stuck trying to load the preview), however since then it has progressed to downloads refusing to download and the hamburger menu in the menu bar doesn't react when left clicked at all.
