When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

When playing a video on YouTube the video is choppy and drops around 2/3 of the frames. This happens on every video that I click on.

I have found that if I double tap to jump back 10 seconds in the video it will no longer drop frames and play smoothly, but if I change the playback resolution it returns to being choppy until jumping in the video again.

I am currently running the latest stable download from the play store, and my phone is a OnePlus 8t.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

When displaying an iframe video in a popup, clicking the close button and other click events do not work. This issue only occurs in the Firefox browser on Android, while it functions correctly in the Firefox browser on iOS.

Is this a default behavior.

I am having a significant issue with firefox draining my battery. I used chrome up until the new year and then switched over to firefox from chrome. Overall I love firefox so much more. The format is way more pleasing. I love how it easily signs me back into everything, BUT IT DRAINS MY COMPUTER SO MUCH. Like i used to have an 8hour + battery span my laptop neverrr died. Now I get through MAX 2 hours of full use before needing to charge, and maybe 4 hours just having it at school but not using it.

I thought my dell suddenly started crashing, ran all these tests, and then I realized the only change was that I had started using Firefox... So sad I think I am going to have to leave it.

I read a lot of articles and did everything suggested. my graphics is webreader , i turned on all the suggested features, i have 2 extensions , the only thing I could maybe think of was that I use an animated theme so maybe that was killing the battery, but like if I can't use my theme than whats the point.

Hello there! Please can someone help me? On my pc, lately, when I move an email from my Thunderbird Inbox to a folder, the message does 'go' from my Inbox, but it does not re-appear in the folder. In fact, the message seems to disappear! However, the message tally count for that folder indicates that the message should be there, but it isn't visible. It's obviously been happening for a while but I don't know when it will have started. In the attached image, the folder 'Chatham, Cape Cod' shows that it should have 10 messages in it, but you'll see that the folder is empty, no messages are showing. In fact, all of the 3 folders 1) Boston, 2) Chatham, Cape Cod, and 3) Virgin Atlantic show that they have messages in them, but on opening each folder, each of those folders is empty. I should add that, on my phone or ipad, when I view my folders, all of the messages are visible. It is just on my PC that the messages are not visible. I've uninstalled Thunderbird and reinstalled it, but that didn't help. And I don't know what else to do! I'd be so grateful for help as I'm not techy and, as I work mainly from my PC, it's proving to be difficult not having all of my messages visible in their folders on my PC. Fingers x'd someone has a solution! Many thanks.

I have used Thunderbird for many years without a issue. But as of a couple days ago I have been getting errors when I open Thunderbird. 1) It always ask me to login even after I save the password to always login. 2) I get this message: "Login to server imap.comcast.net with username caulkerguy@comcast.net failed." 3) Then I get this error message "Alert from account caulkerguy@comcast.net 1014." I have checked all my Server settings and all are correct as per your online settings. I have searched the web and have not found any fixes. Are there any fixes or work arounds? I would hate to stop using Thunderbird as I really like it! I have included 2 screenshots.Thanks for any and all help! Mike: caulkerguy@comcast.net or caulkerguy@gmail.com

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

"Enter Password" box no longer comes up when I start up Thunderbird. One account has password saved but the other doesn't so I cannot access emails on this account now as they won't download without either a saved password or (as I usually do) entering a password. This affects my husband also so not just something on my account. This happened around the 20th December. I've searched through Thunderbird settings but I can't find any way of adding a password directly into Password Manager - only edit or delete. So I can't fix the problem we now both have with accessing new emails. So - any suggestions please or is there a fix coming?, kind regards

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.

Hi!

I get repeated messages that I use an old version despite having downloaded the most recent version. When i try to start Firefox it won't start, I only get a message and the precise wording of the message is" You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox." Then I get two choices, either "Exit" or "Create New Profile". If I choose the first, I exit. If I choose the latter and create a new profile then I loose my bookmarks and browsing history. Appreciate any solution you might have

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

Hello, After update Thunderbird quick filter became very very slow.

If you type in quick filter field two words. At the beginning is being shown random results not connected with typed in words. Then in 30 seconds or later are being loaded correct results. Not possible to use like this. It's local search on normal PC (with CPU AMD Ryzen 5 PRO 4650G, 24GB RAM) filtering must to work fast. Could you fix that issue?

Thank you

It started today, with no new software, or addons installed. Version is 119.0 64bit.

I tried: - troubleshooting mode - disabling all Addons - uninstalling and re-installing Firefox - setting both browser.tabs.remote.autostart and browser.tabs.remote.autostart.2 to "false" - uninstalling Firefox, manually deleting everything Mozilla related in the App-Data, and Programs folders and finally re-installing Firefox

At least the last one should have worked? I am at a complete loss and rather frustrated.

about:crashes claims that there are no submitted crash-reports.

Hi there,

My grandmother on this account keeps receiving a enter primary password alert on her Thunderbird / Bigpond account. We've tried everything and when following the prompts to reset (tools > developer tools > etc) it won't come up with the evaluate button or reset button. We've tried the online sources but no success and she can't access her emails on her desktop. Please let me know what we can do !
