Firefox Community Forum

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.

On February 22, my bank, (5/3.com), decided a transaction I was making using my debit card was suspicious and locked my account. I contacted them and informed them this was a legitimate transaction and they unlocked my account, and everything seemed to be alright, my card was working all seemed well. That is until I tried to log in and check my balance and I could not get in. I then contacted the bank customer service and spent over an hour with them attempting to resolve this issue to no avail. The person on the line suggested that I try another browser so I connected to Edge, entered my log in and password, (which is stored in my Mozilla), and it went right through which proved two things, my password and login were correct and the issue is with Firefox which is very odd to me since it has always worked perfectly as long as I have been with this bank. Again, this issue began when the bank lock my account and as a side note they did the same thing with my wife's account, she called and they unlocked her account and every thing works as before and she can still use her Firefox and gets right in to the same bank with no issues but not me. Again, this started on the date I provided above and I can use any other browser and I get right in with no problem but I am a loyal Firefox user and I want to only use Firefox so I hope you can assist me in resolving this aggravating issue!

Thank you and Kind regards, George Morris

The most recent update has caused an issue with LinkedIn. The problem only occurs with Firefox, not with Chrome or Edge. Do you know what it is? How to fix it? The profile photos are being overwritten with the name of the person and title.

In Firefox (up to date yes) when I embed a YT video to the forums I use, it comes up with an YouTube Configuration Error 153.

How do I fis this? YT embedded on Chrome & Brave etc play perfectly, but Mozilla always sends me to YouTube itself.

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 get all other websites and I used to access couchmanagers.com on Firefox. But recently on about 90% of the clicks to this site I do NOT receive the "Current Auction" and "Chat" pages. What can I do to resolve this issue other than use another Browser. This site works fine on my Fire Tablet and everyone else computers and tablets.

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.
