I've just opened one simple Web site (in addition to Mozilla), and already CPU usage sits at about 20%! Please refer to my recent posts here at "Why is Firefox Suddenly Taking Over my CPU?" for the problem description. I'm re-posting simply in hopes that I can "send data" on this one from outside my sandbox. Regards -- jclarkw

When playing a YouTube video and attempting to open a new tab, Firefox consistently crashes. This was also occurring with Picture-in-Picture mode.

Has anyone else encountered this?

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

Hello, I hope somebody can give me some guidance about two issues that are driving me crazy. To provide some context, I use Firefox to work from home and my primary interest is accessing government and bank sites from my country to fill out tax forms and pay said taxes, therefore the browser built in provisions that deal with web page development, shortcuts, Artificial Intelligence, Social Media are utterly useless to me. The issues are as follow: 1. I regularly access the website of the federal tax authority of my country and local state hundreds of times each day. After a while, normally two months, Firefox starts to behave like a drug addict: It develops a resistance to the security cookies from these sites that worsens over time, until eventually the websites plain out kick me as soon as I log in. The only workaround is to use Privacy Mode or another browser until Firefox starts to behave again. In 2026 this started to happen with the bank website too. 2. After a fit of rage after a failed task I was in the process of attemping to destroy the mouse when reason finally prevailed but not before I got another issue with Firefox: The browser now prints (To PDF and paper) every single item from dropdown menues in webpages that cointan these elements. I already tried re-installing the browser, doing a clear install, erasing cache and cookies, deleting profiles. Thank you for any guidance.

Why is Firefox blocking my access to certain form fields such as User ID, Email Address entry and Security question prompts to web accounts I have, such as a Rumpke payment portal? It blockeed my access so I cannot so you now for invalid tries because I could not key into them and locked me out of my account- sorry.

When I select a line of text, normally it would get deleted/overwritten when typing a new line of text, but when I select text in Firefox and begin typing again, it simply deletes the first word in the selection and keeps the rest. Is there a setting to have ALL text selected deleted/overwritten when new text is entered? Selecting one word overwrites the whole word but when an entire line to be deleted is selected, only the first word is deleted and typing begins where that word ends.

I have been trying to get Firefox to clean up everything when I close it down,

It is so hard as if purposely a 1000 development team have worked on making it impossible.

When I close it down, it must be completely sanitised, no previous site visits, login names, passwords, suggestions - nothing.

And I should be able to achieve that with one button press, not have to go through a thousand individual settings.

I have now spent an hour checking and unchecking buttons, it is crazy. For example I go to the passwords, I have to delete each and every one individually. Maybe there is another screen somewhere, but when I want to interact with "Passwords" I naturally go to "Passwords".

And still, when I go to gmail, it autofills the gmail account! Where did that come from? I have spent an hour trying to make sure it deletes everything when it closes down.

And it should leave no trace on the PC. no temp files, nothing.

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

The question has been edited after doing further testing on the issue.

During the last week or so I have encountered the issue that one or more of my Firefox profiles keep resetting after every update.

I noticed there's couple of threads with similar issues already but the generic profile restore instructions are not helping at all since it seems that Firefox is actually wiping some files. I'm not currently sure what causes the files to be wiped, but it's either related to rebooting the PC or starting / closing Firefox. The file deletion also doesn't always hit the same profile either.

I'm running Firefox 150.0.1 for Arch on CachyOS.

I did a clean reinstall of Firefox. After the install I created 2 new accounts in addition to the one that's pre-created on install. All of the profiles work as expected at this point.

The profiles seem to have files in three places

• $HOME/.cache/mozilla/firefox
• $HOME/.config/mozilla/firefox
• /run/user/1000/psd/

The issue seems to be that after a reboot the files under /run/user/1000/psd/ are missing. Both of the other locations seemingly are unchanged but under $HOME/.config/mozilla/firefox the linked files claim no target in /run/user/1000/psd/ is found.

When looking at the missing files, it seems that in total 6 folders have been wiped at the time of testing. All of the wiped directories were ending as ".Profile 1" or ".default-release". Directories ending with ".Profile 2" or ".default" were still there. At this point I'm not sure what is causing this but it seems to explain why the profile is inaccessible.

Manually restoring the files under /psd/ seems to fix the missing profiles completely.

The past few months, I get a periodic issue with Firefox. I've done some searches and looked, but nothing anyone has suggested seems to work. I also run the Chrome browser on this same computer (I have 2 Etsy shops and prefer to stay logged in to both of them, so 2 browsers are a must). NOTE: I've been doing it 'this way' since the early 2010.

This is a new Dell Windows 11 desktop. No issues with the computer. The browser is up to date.

I keep from 3-8 tabs open at a time. My Etsy shop. My email. My shipping supplier. Etc. None of these run a lot of hot graphics or anything. Suddenly, I see 'sparkles (the only way I know to describe it) on some text boxes/etc) then...the address bar starts with the flashing pink/magenta.

Appreciate some help in getting this to stop. Again, doesn't happen on the Chrome browser. Only Firefox. I've used Firefox for a very long time and appreciate it. So I hope that I don't have to go to a different browser.

Thanks in advance. I've attached a photo of what I'm seeing. Note that this vibrates...not static.

Hello, I’m currently having an issue with Mozilla Firefox.

It says it’s impossible to "bookmark this page" either via the icon or the keyboard shortcut CTRL+D. Additionally, I can’t create folders to sort my existing bookmarks, and I can’t add a bookmark to the personal toolbar. It feels like everything is locked. I’ve already uninstalled and reinstalled the browser, and I’ve removed all my extensions, but the problems persist.

Current Mozilla Firefox version: 146.0.1 (64-bit)

Despite trying all available solutions, importing bookmarks from Chrome does not work in this firefox latest version 150.0.1. When importing Bookmarks from Chrome, the Saved Passwords file is fully imported and shows 163 Nos. imported. But on opening Firefox, nothing is there. No folder contains imported bookmaks. Tried importing several times, but to no avail. Uninstalled, restarted PC and reinstalled firefox. But importing Bookmarks and Passwords from Chrome sucks. I am fully aware of the procedure. So no more detailing needed. Using firefox since the last 16 years. But the software makers are simply spoiling a good browser by deliberately creating issues. Tried importing from saved html file of bookmakrs, but that also is not helpful. Why Firefox is deliberately causing such errors with updated versions? Please release next version after thoroughly checkining this importing feature and ensure that it works correctly. I tried uninstalling, restarting the PC and reinstalling with with full offline installer as well as online installer. Nothing helped. Chrome works smoothly. Earlier firefox did not have any such issues. With each update, problems after prblems started creeping in with someone deliberately tweeking the software and spoiling a good browser. Please look into it seriously and provide a solution.

When on the home screen and with setting "3 rows" for shortcuts, the third row has two missing slots and I cannot add extra ones to fill in the gap. I don't want to make it "4 rows" as it will show an "add shortcuts" button which I feel is unnecessary if I plan to leave the 4th row empty. It is also happening on LibreWolf

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

Good morning. I am looking forward to the VPN service being offered for free through Mozilla. I see that the rollout has happened in the US but I haven't seen it yet. I have been using Mozilla for years and wasn't sure if the US had been fully covered yet or not. Thanks and have a good morning.

While submitting online forms for opting out of data brokers getting the following error: Invalid Turnstile captcha response. Using Windows 10 and latest Firefox, tried putting Firefox in Troubleshooting Mode which runs without extensions and searched for online solutions, but no help.

Richard

so i had a bunch of bookmarks saved, and when i logged in today they are gone, replaced with a message For quick access, place your bookmarks here on the bookmarks toolbar. manage bookmarks (link)

so when I use the link I cant restore bookmarks, cant seem to save new bookmarks, and the FAQ section isnt helping, some of the stps they talk about are greyed out in my version, so I cant click on them etc.

Is this a windows 10 issue? Am I the only one having this problem?

Unable to play a video on Hulu with my own Hulu account, which I have had no issues in the past doing, even with all my ad blockers and trackers enabled (Privacy Badger, uBlock Origin, AdBlocker Ultimate, Ghostery, and Malwarebytes). I have tried disabling all of the above extensions, refreshing the website and still no luck. I have also followed the instructions Hulu guides me to via a link on the screen (see attached screenshot) to their help page https://help.hulu.com/article/hulu-power-cycle?utm_source=hulu&utm_medium=error-message&utm_campaign=video-02 None of these have helped either. My internet speed is fine, I checked it through 3 different internet speed testers to verify Also checked my Wifi signal through our Google Home portal. I've searched online for solutions and haven't found anything new to help or in the Mozilla Support forum. My computer/laptop is up to date on all updates and software. Appreciate any support, thank you!
