Creating a brand new profile on a SMB shared drive is making TB almost unusable. Even before creating a mail account it is so slow.

I'm using this version of TB 128.7.1esr (32-bit)

Hi, I’ve been experiencing slow performance on Firefox recently. It takes a long time to load pages, and the browser sometimes freezes when I have multiple tabs open. I’ve tried clearing my cache and updating Firefox, but the issue persists.

Has anyone encountered similar issues? Are there any tips or settings I should check to improve performance on a Windows machine? Thanks for your help!

My download helper has suddenly stopped working icon lights up when opening FireFox (FF) but goes to NO COLOR even when watching a youtube video there is no color to the icon and no media sensed by the app i did not change any settings (?connection? my RealPlayer Downloader has also stopped as well) thx Bob rmarloweaz@yahoo.com

I want to open links in a new tab without being diverted instantly to that new tab. In settings, I disabled the option “When you open a link, image or media in a new tab, switch to it immediately”. Normal links in Firefox behave like that, all well. Images open as well in a new tab without switching to that tab.

But, when I am working in Firefox Inspector, in the code. I want to open an image’s link as well in a new tab, without switching to that tab instantly. And that’s where it fails: it has me switching to that new opened tab.

I tried to change in about:config the option “browser.tabs.loadDivertedInBackground” to “true”, (was: false). But apparently this doesn’t work for links in the code in Inspector. Could someone shed some light about this case, please? TIA!

I am running Thunderbird 128 (any version) on a Surface Pro 9 running Windows 11. After sleep/hibernate or going into energy-saving mode, TB hangs for a period of minutes. Eventually it comes back, but it can take 5-10 minutes.

I do not have this problem with TB 115 on the same machine, or TB 128 on other machines (e.g. running Windows 10 or Ubuntu). TB 115 on the same machine can take a few seconds to come back (longer than on my other machines), but that s OK.

I have the same expereince whether or not I am troubleshoot mode. I have created a new profile with no add-ons (and less acounts) and I have the same problem. I was wondering if it is something to do with the fact that I have 8000 folders, and somehow TB is hanging while it checks all the folders. That account is a fastmail IMAP connection, but I have experienced similar on a backup Microsoft Exchange account (again an IMAP connection) with similar number of folders.

Any help would be appreciated.

Hi. I encountered a problem when browsing previous pagr after google search in android version of Firefox. The procedure for reproducing the problem is described bellow.

Environment: 135.0.1 (Build #2016074239), hg-7c2ff1aa3394+ GV: 135.0.1-20250216192613 AS: 135.0.1 Pixel 6a(Android 15)

Procedure: 1. Search any word(such as "test a") with google. 2. Tap any link showed in searching result. 3. Perform "previous page" gesture(horizontal swipe at edge of the screen), then searching result of "test" is shown. 4. Search another word(such as "test b") with google search bar of google website, not search bar of Firefox. 5. Tap any link showed in searching result. 6. Perform "previous page" gesture(horizontal swipe at edge of the screen).

Expected result: Searching result page of "test b" is shown.

Actual result: Searching result page of "test a" is shown.

Other informations: - This doesn't happen with other searching engine. - This do happen without extensions - This also happen in private session - Clearing cache solve this problem for a while but this happen again soon. - This doesn't happen in PC browsing mode

I encountered the same phenomenon when I searched the word that I've searched before. So I doubt that google search and cache algorithm of Firefox is not compatible.

I look forward to someone's reply or any information.

Hi, for the past couple of weeks firefox is causing the GPU to block firefox when trying to play a youtube short preview by hovering over the short. The screen goes white and then returns and it happens again if you leave the cursor over the short. After a few of these, the message comes up that the GPU (nvidia in this case) acceleration has blocked access to firefox. This will happen every time. The issue doesn't occur in chrome. The issue doesn't occur if firefox is started in troubleshoot mode. If I run in regular mode and manually disable my one extension (keeper) and the two plugins - widevine codec and cisco openh264 codec, the issue will still occur. I have no other add-ins. I have updated firefox and the nvidia drivers to the most current. The gpu is nvidia geforce 940mx with intel hd graphics 620. I am running 64bit windows 10 home on an hp envy laptop with i7 chip. Any ideas? Thanks.

After upgrade on iMac to Sequioa, my search bar no longer will show results for longer than a nano-second. Have tried to reach out to Apple Care but they are unable to help since not their product. Hard to describe - screen sharing is optimum if able :)

Hi, in windows 10, while I am launching Firefox - if it does not exist yet - a new read-only file is created on the Desktop. This file was created time ago by myself (so its name does not matter much and it contains only a small empty branch). I can't delete it as far as I don't have the rights to do it. I tryied used cmd console and powershell to fix it, but nothing works fine. I run my antivirus, no more result. Tried to trash this file using external programs, same issue. Tryied to change the rights of that file, to reinstall completly FF, nothing seems to be useful. Possible way to solve it : I clean up my C: last week because I wanted more space and a better organization (moment from which that problem began). It is like Firefox was needing a file in the Windows tree and as he couldn't find it, he creates it because he need that this file exists. Regards

The past weeks/months I do not see any square check boxes where they are supposed to be. When I click in the space where I know ther is supposed to be one, a check mark does appear, but it is annoying. Buttons remain empty visibly when I check it. No dot appears, but it does register that I clicked it. Also annoying. It's in automatic, light and dark mode the same

P.S. The same with the check box (email me) on this page, but now I see a check box but not if I clicked it.

Hi, I have an issue that is very annoying. I recently upgraded from brother HLL5200 to HLL5210 printer. Since that upgrade, all emails printed via logmein/thunderbird/brother printer are printing in 1/4 of the normal size (tiny print in top left hand side of page). This applies to emails I try to print, as well as attachments. I have no other printer, so I cant test elsewhere. Thunderbird troubleshooting mode does not help. Brother studied it and said its not a printer issue. Logmein studied it and said its not a logmein issue. My tech support guy thinks it may be a driver incompatibility between logmein and thunderbird. Can anyone help? Please contact me at nathan@nrosencanada.com thanks!

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.

Firefox has recently become unreadable--it is blurry, then clear, blurry, then clear. It has become unusable. I've moved on to Edge. After much research, it is apparent that this is a problem unique to Firefox, who hasn't bothered to address or correct this issue. No more Firefox for me:(

Hello! I have multiple issues with Firefox after YEARS and YEARS of usage.

1) There is always a problem logging into sites that require captcha. This started happening a few months ago. So sites will not open in Firefox, but there's no problem with using Chrome.

2) All of a sudden, when I open and download PDFs from websites, the documents are black. I've gone in and disabled dark theme, but that hasn't made a difference. Again, this is a Firefox issue because it doesn't happen when I'm using Chrome.

Hoping you can help me with both issues. Thanks much!
