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”?

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

My laptop glitched while doing a Windows update and it chose to not load certain apps upon completing the update. Mozilla Firefox was one of the apps it chose to delete and I lost all my bookmarks with my login information to all my accounts, can I retrieve those?

I have recently noticed that I can no longer see the "comments" sections on various "News" websites. I first noted this with Townhall Media sites (Townhall.com, Redstate.com, Pjmedia.com) and now Foxnews.com. What has Firefox changed that has resulted in this issue? Most of these sites use Disqus for comments. I have tried explicitly allowing content from these sites. I've been using Mozzila products since the advent of Netscape. Always found Firefox to be superior to other browsers, and I'd like a little help in finding out what is causing this problem. Thanks.

Can not find how to do FireFox on the new setup. HATE the new Fire Fox emailing format!!! One thing is the ongoing back and forth with others I sent an email. Usually to reply, just had to click on reply and send my response fro the just sent email. I HATE THE NEW SET UP!!!!

I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

Regards,

Firefox continually refuses to open, and I have worked all the suggested solutions once again. I used it for a few hours this morning, switched briefly to Chrome. Went to go back into Firefox, and it wouldn't open again. Did all the work arounds....uninstall, reinstall, even system reset to the previous day. Still won't open. I am so disappointed at having it behave so unpredictably. I sometimes sense it is related to updates....almost afraid to reboot my computer sometimes because it will not open afterwards. My recent install attempt appears among the public users, which is not the case as mine is a private PC. The Mozilla Program itself, however loaded to the 86 bit program files. Not at all sure to proceed at this point.... getting forced over to Edge it feels like....

When playing any Ren'Py web build on Firefox Windows, the frames freeze while entering inputs. Depending on what is being displayed on screen, sometimes it will still continue despite the mouse movement, but most things just completely freeze up. Once the inputs stop, the frames will skip ahead to where they should be. This only seems to happen on Windows, as I was told it is not repeatable on Ubuntu using Firefox. This is also not an issue on Chromium based browsers.

I have an issue that's been annoying the crap out of me and I haven't been able to find a solution. I'm hoping someone here can help me out.

I want to drag an image from one tab into the upload field in another tab. This works fine in other browsers, but not in Firefox.

For example, I'm posting an item on Craigslist. I have pictures on the item in Google Photos. I would like to drag the image from the tab showing Google Photos to the upload field in my Craigslist post, but when I do, nothing happens.

I get the same behavior regardless of what web page I'm dragging the image from or what website I'm trying to upload to.

I have been using [edited] @comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered [edited[ @gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered [edited] @gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the [edited] @gmail.com account. Would appreciate any help you can offer.

I used to use chrome. There, when i add a bookmark, the title and the URL are prefilled. Which is very comfortable. Why is this not a feature in firefox? I always have to copy paste the URL and enter an own title. Chrome has become very slowly on some websites, while firefox does not slow down on those websites at all. So i want to stay with firefox. Good job, team. But the bookmarking UX is improveable.

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

Almost daily I get a message to download or dismiss update. When I dismiss the message, it continues to pop up. When I hit download, nothing happens. This is locking up my computer at times & slowing everything down. I actually don't see the need for daily updates. What is causing this and how can I stop it?
