Hello.

Typing anything in URL (address) bar causes my CPU spike to 15-20% shown in Windows Task Manager, and up to 80% shown in Firefox Task Manager. I have 8 core / 16 threads CPU running at 4.0 GHz, so typing text in browser taking 15-20% of that is rather bizarre to me. OS: Windows 10 What I tried: - disabling Firefox Accessibility Service - hardware acceleration on/off - troubleshooting mode

Don't have same issue in other browsers (Chrome, Opera) Any ideas what else that might be?

The title already says it all. Whenever i have some sound or video running in any tab, clicking on certain things like other videos or animated stuff in the same tab or another one causes a small interruption in the sound/video. Clicking a lot of times results in sound and video stuttering. I does not appear when i just click another link.

I already tried updating firefox, reinstall firefox, even downgrading firefox. This problem only appears in firefox and only on this device. I would be very thankfull for some advices, because this is really annoying.

Just used sync in the past month with no issues.

Logged into sync today, immediately after logging in, the error message "Session Expired -- Sorry something went wrong. Please sign out from the browser window and try again." See attachment to see exact error message.

This exact error message appeared on both my PC's when I tried to sync between them. Any thoughts on what is taking place or is there a know issue with Sync from Mozilla today?

I used Samsung smart switch to transfer data to new phone. When I tried to sync Firefox on new phone with my PC, old phone and tablet I was asked to type in the authorisation code. No matter how I have set my e-mail accounts no e-mail is received in my spam folder or in-box. There is no way to contact Mozilla to resolve this. I have not received any e-mail to state that my sign in was blocked for security reasons nor have I received an error code. I setup a bugzilla account and tried to request that my account be unlocked but there was no way to do this. All it has done is to create an entry that I reported "Zarro Boogs found". How do I get my account unblocked as the advice on the help pages is no advice.

Hi: I've used Firefox for years without trouble and I've even given money! However, I think the last update has prevented my banking site from operating correctly. In Bill payment you choose who you want to pay and fill in the amount. This still works. I move to the month, day, year boxes. If I click, say, on the month box I get a dropdown but selecting the month nothing happens. Ditto with day and year. The day box shows 1 and the year shows 202 and nothing changes when using the drop downs. Can't manually fill in the boxes. At first I thought it was my bank but they said there were no reported problems - they would! So tried Brave and Edge. Both worked perfectly. Tried it on my laptop rather than desktop and same problem using Firefox showed up. I hadn't fiddled with any Firefox settings. What to do? Thanks Donald

Hello everyone.

I've been having some issues with Mozilla lately. I don't know if my CPU is in bad condition or not but, when I change tabs through my Windows, say changing tabs from Mozilla to Spotify and changing it back to Mozilla, my CPU gets very full, causing my cursor to lag, and Mozilla to be unresponsive for a couple of seconds first and it gets kinda worse as I continue to use my PC, causing the lag to occur for over 10 seconds.

I have seen some similar complaints on the web but they date back to 2014ish times.

What do you think? Is it somewhat my CPU's problem or did Mozilla's handling get worse over a patch or something?

I enjoy Mozilla and don't want to quit using it. Any help would be much appreciated.

I have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

I have been successfully using FireFox for many years, recently we downsized into a Condo,now 81 years young. I have FireFox as my default browser choice, but it only lists Google on the search bar, when I type in my search in the box under the Firefox name it immediately jumps up to the top of the page Google browser.

How do I get back my screen to use FireFox as my search engine ?? I have tried to change it but will only give me two options Google or Google ?? Is it possible to go back to the screen and try and start again??

Many thanks to anyone who will give me info as to how to rectify my problem, be gentle with me as I am efficient in using the computer but less so trying to solve my problems. Robin

I am creating a split-flap. It works fine in Chrome, but in firefox, during the second rotation period, it is not smooth as in chrome. How can I fix it?

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

EMAIL VERFICIATION CODE ISN'T SENT\ tried a few attemtps

I formatted my laptop, and now i downoladed mozilla, logging in... and waiting for verficiation code for mozilla sync account for years, please help

Evening from Johannesburg. Please can someone advise as to when i will receive the verification email? I have tried numerous times and i am yet to get one email to action this. First attempt was 05th May. Another, today. I am still waiting and have checked all folders in the said email to use by yourselves.

Following site is immediately hijacked to a scam site asking for login apparently to access private info. It happens with Firefox (only) whenever security setups are set "not to track", "not to prompt for passwords", "not to prompt for credit cards" "no history" "reset of cookies at logout" etc.. then the site below: http://thaimassage-herborn.de/ is redirected to SCAM SITE: https://xb7.serverdomain.org/admin/index.php appearing as "Adminpanel" asking for Login etc..

At the same time following site is partially blocked on the news banner pictures, with a white sheet over them, whenever down scroll is hit. https://www.tgrthaber.com.tr/

Only by resetting firefox deals with the issues. But ofcourse with the reason, above security settings removed.

Virusscanner was not able to detect this hijacking or the reason behind.

Is this a firefox software issue? Is there a way to resolve this? Thank you already for any support or suggestions to resolve.

im afraid to download anything. i should not have to download firefox browser, i have been using this acct for years. i tried to update ccleaner last nite and windows defender caught a trojan but removed it right away all other places i have been were fine today what happened to my firefox and duckduck go etc

Can someone confirm if mozilla-api[.]com is an official Mozilla domain? It was registered 7 months ago with Namecheap registrar. I am unable to find any overlap with official Mozilla infrastructure and I suspect this is a malicious domain.
