I am trying to free up some disc space, so I ran Disk Cleanup, but no improvement.

It shows over 430MB Temporary Internet Files, all of which are under a padlock icon. The size just keeps on increasing from day to day.

How can I remove some or all these Temporary Internet Files and regain disc space?

I use Xero accounting software and used to be able to view pdf within the software up until the recent update. Now it just sits with a spinning wheel. I've found that if I change the setting within Firefox to open the pdf within Firefox the issue is fixed in Xero. But then all pdf's open in Firefox instead of the usual Adobe. This breaks other workflows within my organisation as I need to email the pdf straight away when I download it, so my Windows was set with Adobe as the default for opening pdf's but now Firefox has taken that over. There does not appear to be any way to email the pdf from Firefox other than to save it and then find the file and email it from there which is very time consuming. I don't know what has changed in Firefox, but please can you fix it. I see I'm not the only person with this issue.

https://hbr.org will not allow me to sign in using Firefox. It does not recognise my email address if I use the Lost Password option. MS Edge allows me to sign in to https://hbr.org without problems. I have listed hbr.org as Exceptions in tracking protection, cookies, and blocking pop up windows

Last year, I never could get the info in to register, but it did let me do my taxes on it. I hope it lets me do mine this year. I really need to get it done, I have more to do than usual. While I was writing I saw someone ask if Mozilla and Firefox were the same, but I did not see the answer.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

If I send mail to curly@stooges.com, it gets put in the curly@stooges.com mailbox -- created if it doesn't exist.

If I get an email from curly@stooges.com, it gets put in the curly@stooges.com mailbox -- created if it doesn't exist. If I reply, the reply gets put in the curly@stooges.com mailbox.

I have one and only one SMTP account. I have 1,000,001 POP accounts. Mailboxes and accounts have no relationship.

This is a serious question, not a joke.

Ever since the latest update, whenever I right click the Firefox icon in the pinned tiles on the Windows Start Menu, the options to launch a new tab, new window and a new private window don't show up. They show up when I pin Firefox to the taskbar but not the Start Menu.

Some sites I use will not let me use them unless I stop using add blocking. I have not installed an add blocker so I am thinking it must be one in Firefox. Assuming this is true, how can I discontinue the add blocker at a specific site so I can access/read/use its contents. Thank you in advance for any help you may be able to provide. Ken

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

I'm attempting to set up Firefox in a newly installed OS and have logged into my Sync account. Many aspects seem to be loaded in, but the status via the Settings is stuck at "Syncing..." despite waiting several hours. Quitting Firefox results in a crash window popping up.

There are no files in the weave/logs directory. The weave/failed directory has multiple json files; most almost completely empty. addons.json has an ID, but that's pretty much it.

Deleting the .mozilla directory and starting over yielded no change in behavior.

Any help would be appreciated. Thank you.
