I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have two extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

upgraded to Windows 11 , and thunderbird has not worked since then !

PLEASE call me in Sydney Australia, or send me a local telephone number of someone who can help me !

I want firefox to open a .ics file in google calendar rather than the "Use Calendar (default). I've already run the script linked here : https://support.mozilla.org/en-US/questions/1196085 to register the webcal protocol handler.

The webcal It shows up in the Settings / Genera / Applications list See attachment "Webcal.jpg.

But earlier in the applications list, there is a "Calendar" entry that only allows me to go to the "Use Calendar (default) or ask or save. See attachment Calendar.jpg

It seems like Firefox uses the Calendar entry before it gets to the webcal entry and so it always opens the default windows calendar application.

Help! How do I get firefox to use the webcal entry and not the calendar entry.

Thank you.

If I Close (not Exit) FF and then later Open it, the new Open page is a different size and screen location than when it was last closed (I have to then reposition the page manually).

Is there a ABOUT:CONFIG setting I can can change to stop this?

Using Thunderbird version 115.11.0 (64-bit) with Windows 7 OS and THREADING TURNED OFF.

When I receive a second reply to an email I've sent via one of my email service providers that uses an outlook365 server, my thunderbird view hides it beneath the first reply unless I manually intervene by clicking on the "greater than" sign associated with the first reply. When I do click on the first reply the greater than sign spins clockwise 90 degrees and the second reply appears below the first as if it were in a subdirectory.

The above behaviour is very inconvenient because I am prone to missing the second reply and have trouble anticipating its existence. Admittedly the unread second reply does change the first reply's text property to "bold" but I much prefer to see the new message without having to manually click on everything bold to check.

Another email service provider I use also has an Outlook365 server but second replies to emails are not hidden in its associated thunderbird inbox?

Can anything be done in thunderbird to stop this "feature" or is it absolutely fixed by service providers?

I'm using Firefox focus on my iPhone.

iOS is the latest version of 15 and 16.

Question 1.

We use it as a content blocker for Safari.

When I open iCloud notes, the characters are not displayed. Only the photo will be displayed. If you remove the content blocker, it will be displayed normally.

The language used is Japanese.

Can I avoid it by setting focus?

Question 2.

I thought I'd check the iOS version.

If you enter iOS 16.7.8 in the search field, you will get a URL error.

I can do it with other browsers, but why can't I do it with focus?

Is there a solution?

Once you add a new account, you have to race to open up the settings and turn off the "Download all mails" setting that is hardwired as the default. Even after having done that, I am left with GB of copies of mail messages that I don't want to store on my local system.

How do I get rid of those local copies? Compacting doesn't seem to do it - there's no "Compact now" button in any case. I don't know what "when it will save over N MB in total" means, exactly. Save compared to what? Now 50% off!

Likewise, if I have Message Synchronizing (Keep messages in all folders etc) turned off, but Disk Space - Synchronize all messages locally regardless of age is still selected, is it going to download copies anyway or no?

If it will download anyway, or if it already did download, if I change the Synchronizing setting to "only the last 30 days" will it remove the older local copies? When?

The only "recover disk space" option deletes both local copies and originals on the remote server.

There really should be a "purge local copies" action available in the client. It may be that it is OK to go out to the OS and remove certain files myself, but maybe it won't be in the future. Every note that is about "Simply open a Terminal window..." describes specific files that don't quite match what I see here in May of 2024 on a Mac. But the tool itself knows what can be removed safely.

I have pictures that are slanted. Chrome, and Safari don't do this, so I know it is something with Firefox. Every once and awhile Firefox also has little square dots that appear s’ for ‘Firefox’

I started with Firefox on android, when i finally got a pc i decided to sync my data. This resulted in the loss of all but 1 of my passwords and Ive spent 5+hours trying to get them back. And i idk if i can. But with the help of this extension (https://addons.mozilla.org/en-US/firefox/addon/about-sync/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search) about-sync i can see the logs of them being deleted(where pics are from). Why cant i just revert this or have instances to revert back to?

I must utilize a radiology based website application that works best in Firefox. I utilize 3 monitors on my system and have Firefox browser working on Monitor #3. Unfortunately Firefox opens the popup windows in Monitor #1. I cannot find a setting anywhere that would force it to open the popups on the monitor that is running the Firefox browser. I do not have this issue with Microsoft Edge, Google Chrome just this browser. I only use Firefox for this application because of this. However, I must use it 4-5 hours a day and this is extremely annoying. Is there any way to fix this issue? In today's technology and the fact that most of us use multiple monitors, I would think this browser would be up-to-date in its options and ability to handle this. Any help would be greatly appreciated.

Tēnā koutou (Hello everyone),

I deleted Firefox to re-install it after playing with profiles and that not working how I wanted it to (yet). I uninstalled the app from the applications and the library on my Mac and reinstalled Firefox. Now when I open Firefox it says that it's up and running but no windows actually open up for me. I have uninstalled and reinstalled it again and it still won't open windows. I have to force quit Firefox as nothing shows up in my top tool bar to even show Firefox as open.

How can I get Firefox to actually install and be functioning on my computer again?

Running (as of an hour ago) macOS 14.5 (was using previous up to date OS when I installed Firefox again.

TIA

On my Android phone, the "close private tabs" notification keeps reappearing no matter how many times I tap it or swipe it away. Only way to get rid of it is by force stopping Firefox. Weird thing is that this issue doesn't repro 100% of the time either.

This is happening on Firefox 126.0, on my S23 Ultra running Android 14/One UI 6.1

Hello, my Cox email account was migrated to Yahoo mail. I can receive emails but now I can't send emails from Thunderbird. I've triple checked server settings. Please help. Thanks-Vince

This is the message I get and it does this with all email addresses.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Best regards Andrew Sambrooks

Hello Support, when I create an email in my primary email account (karl.volger@gmail.com) and sent it out, it also shows as sent out in a different gmail account. Any reply is being sent back to me is not going into my primary account, but to the other account, my email is shown being sent from there, and not from my primary account. All the settings in my primary account are shown the correct settings for sending and receiving emails. The only thing I did notice that I have dual folders in the primary account of Drafts and Sent..... Please see the attached image.

Thank you and best regards, Karl Volger
