I Have Had It Installed On Microsoft Edge For About A Year With No Problems. I Had It Installed For About 3 Months On Firefox Then I Needed To Install It Again & I Get The Above Messages. Why Is It Doing This? There Hasn't Been Any Harm Done To My Computer. Also Firefox Needs A Customer Service Phone Number For People To Call & Explain Their Issues It's A Lot Quicker & Easier To Solve Your Problem.

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

I have a desktop and a laptop. Desktop crashed, so rebuilding.

Firefox on both, settings same on both. On Desktop - Last Pass will not appear. On laptop, same as it always has been.

Image below from my Desktop without the Last Pass icon there.

I've downloaded the LastPass Extension from Mozilla a couple times.

Help, please.

Very weird.

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

1) Youtube stalls out. Seems to be preventing or blocking the front ad from running, ... but wait long enough, Youtube video will play. This happens on all my computers, Win 7 and Win 10. Problem been going on the last 30 days.

2) In Win 10, Firefox browser never shuts down when I close it. Must go into Task Manager & do a "End Process" to kill it. I do make sure Microsoft Edge Browser is Disable. It wants to run all the time too. Thanks for your efforts. Been using Firefox since 2002.  :)

Is about:config > app.update.auto set to false sufficient, How to Disable Firefox Update Notifications: A Step-by-Step

Or how about the registry? Turn Off Update

alright guys you need to fix your browser, it crashes everytime i try to play a youtube video.. i searched tou site for fixes and NOTHING worked. you vanilla version of the browser was perfect then yall had to go and do the microsux thing and screw it all up by adding this that or the kitchen sink. i have submitted numerous reports yet no resolution. if you guys dont fix your crap i will move on to another browser and recommend to all my friends n family to do the same.

I use Firefox to access my bank account, and it autofills the personal id number, and, when I click, the 6 digit code, which I allow it to store, because no one else has access to this PC. BUT, I had to take it in for repair, and give them my Windows login details. When I got the computer back, I went to the bank login page, and the autofill was a different personal id number. Does this mean that somebody used Firefox on my machine to login to their account? Or could a reboot have meant that Firefox randomly changed the PID number? Thank-you for your help.

All of a sudden I am not able to download files on my MacbookPro in Firefox. I am using Version 126 on Mac OS 12.7.5 Monterey.

Downloads are working if I use Safari, but I do not use it. I just used it for testing purposes. Is anybody else having this problem? I've already "refreshed" Firefox per their suggestion.

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

I am a web dev and have a user download link to an excel xlsx file. On my own system it downloads fine in Chrome but in firefox ot displays the raw contents. Is this a FF setting?

Searches in Oregon always default to Seattle, even if I put an Oregon city in the search bar

Cannot locate any Oregon businesses or restaurants in oregon

Going to troubleshooting page deletes this entry Don’t know what else I can do

Firefox does not retain email login addresses for Fastmail email webpage.

I have used Firefox and Fastmail for many years and this has never been a problem. When I opened Fastmail previously and placed my curser on the email address box I was always presented with a choice of three or four email addresses. However now I am only presented with the first email address I entered since the Fastmail/Firefox upgrades.

I have contacted Fastmail about this and they suggested it might be a Firefox issue
