I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

Firefox, according to its own Task Manager, shows the browser, not extensions, or particular tabs, using 9GBs of RAM, and 95-120% CPU Usage! This is causing everything to work, as if underwater, typing is slow, hesitates, etc, and opening new tabs sometimes doesn't even happen, and I have to try multiple times, etc. There is no reason Firefox should be using over 100% of my iMac's CPU. Meanwhile, nearly every single open tab is showing less than 1% CPU usage...

I really do want to use this browser, but this kind of memory sucking usage is making really difficult to continue doing.

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

Hello,

All my outgoing messages are bouncing back to me, no matter who I send or reply to, just from one of my email addresses: heidi@benvenutotravel.com

So I cannot reply to anyone nor send, although it shows copies in my sent folder???

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

Hi Mozilla - I just wanted to report some recent phenomena. In the past couple weeks Firefox, and related Private Browsing browser, seem to have developed consistent hangups in fetching data across a pretty wide range of sites. Both my banking sites will not load after logging in to them, just spins and spins. Also some very general searches will not load any results for minutes at a time, I just give up and kill them. I've uninstalled/cleaned/reinstalled latest version, etc, etc. By comparison, these same data fetches in banking sites, etc, work dandy in Duckduckgo browser, which is also a heavy no-trace browser. This ominous to me as I really like Firefox and do NOT want to have to resort to Edge. Duckduckgo browser is very good but doesn't have nearly the menu or favorites sort of features that Firefox does. Can you investigate? This is typical Win 10 system in Lenovo i7, been working like a champ till just recently, no system changes. Thanks.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

The newest incoming email is hidden behind the tool bar at the top of the main mail window. I have to scroll UP to see it. My apologies in advance. I am not tech-savvy. Thank you, A Really Old Fa*t

The company I work for is behind a firewall. Our systems running firefox are unable to send crash reports because of the secure nature of the systems. Is there a way I can send the crash report files that I pull from the "Pending" directory and send them to Mozilla manually? FF version snap Mozilla Firefox 103.0.1 Ubuntu 22.04.3

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I keep getting a popup about using an older version and creating a new profile. I already created a new profile a few days ago so I cannot keep creating new profiles every time firefox deploys a new version and would need to open firefox to update the browser version.

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.
