Firefox Support Forum

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

If I am on a web site and click a link to another page on the same website Firefox opens a new tab rather than displaying it in the existing tab. How do I get Firefox to NOT do this?

can't log in to a number of sites. This time private browsing doesn't work. Trying to log into utility company. PLEASE FIX THIS! I'm having to use other browsers.

Hello,

I've recently encountered a curious issue with my Firefox browser (Firefox version 102.0, Windows 11 Insider Preview 10.0.25145.1011). At seemingly random times it will freeze for between two and five minutes (roughly). UI elements become completely unresponsive and the cursor does not update when moving over the browser window. The window will not minimize. Yet, Windows Task Manager does not report the application as being unresponsive. While never a common problem, any freezes in the past would eventually cause the Windows Task Manager to identify it as unresponsive.

I have disabled "recommended performance settings" and hardware acceleration to no avail. Everything seems perfectly normal immediately before and after the freezes, and I've yet to identify how I can trigger them. I do not recall having made any changes to my browser before the freezes started occurring, though multiple Windows updates have taken place since then. If I'm too impatient to wait I will end the Firefox processes via Windows Task Manager and restart it so I can return to my tabs without having cookies deleted. I have 13 plugins mainly covering privacy/security concerns. Is there some sort of debug tool I can engage to see what's occupying Firefox while it's frozen? I've just found the Firefox Task Manager, and will see if it can offer any additional information during/after the freezes.

Thanks, Logan

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

Firefox often display messages at the lower right corners - only from selected sites.

It drives my crazy - because I have to click on each and ervy one.

How can I select the sites which are displayed or can I shut them off all together ?!?

Please advise !

I know this is not a big problem, but a couple weeks ago firefox updated the browser. one of things it did was changes colors to the top half of the page where the tool bars were. It defaulted to a nice blue which I liked and everything was fine. All of a sudden a few minutes ago it went to all white. I cant figure out how to change it back to where it was.

Up-to-date Firefox on Windows 10 laptop. Today, for the 2nd time in a week or so, the “mailto” function has disappeared; i.e., if I click a “Send email” link on a webpage, the Windows dialogue box to select a mail app pops up. When I check the applications setting, mailto doesn't appear in the list.

The first time this happened, I found online instructions to refresh Firefox and select Gmail as the mail client. I don’t mind doing it again, but I am concerned about the problem occurring so soon after the recent refresh.

I can't get Firefox to store bookmarks on my Mac since I installed Monterey 12.0.1. I managed to find some instructions on your trouble shooting page but they do NOT work. Hate to give you guys up, but unless y'all can help me fix this, I'll be moving on.

Hello, I have a curiosity question, related to privacy. I recently found that eBay was able to confidently identify me when I would not have expected. By the way, I work in tech, often dealing with security and basic privacy. I am well aware of "fingerprinting," but typically that is used to break up people into subsets, or cohorts, not individually identify the user. And of course, even when it does, it typically won't show/tell the user that it has successfully done so. Anyway, here's what happened:

1. I visited eBay using FF's "Private browsing" in "Strict" mode, over a VPN connecting to country "alpha". This was running directly on the host OS of Windows 10, with a non-default (but common) window size, and one very common browser plugin. eBay marked me as belonging to the country of my VPN endpoint, and set the region and currency accordingly. 2. I close the private browsing window, change VPN endpoint to country "beta", and re-connect to eBay. It still recognizes the previous region settings, even though my VPN endpoint is in a different country. Thinking maybe cookies were not wiped until the browser session was completely terminated, I go a little further; 3. Close all browsing tabs, go to settings, and manually clear all data (cookies, cache, etc.). Change VPN endpoint again. 4. Connect to eBay again. It still recognizes me. Note that I have not changed any other signals about the session. Browser window size has not changed, still the same OS, the same browser version, the same browser plugin. I did these tests in quick succession, which could also be a signal to them. But this session did not carry a cookie, and was coming from a different IP address. All cached data had been cleared (supposedly, at least).

Is eBay's fingerprinting just that good, that they actually identify me individually, without a cookie and coming from halfway around the world? Or is there some other tracker or signal they are able to follow me with, to re-identify me?

I was running FF on a transparent virtualization layer, so I just wiped all data stored by FF since the testing started, switched to another VPN endpoint, and just like that, eBay had no idea who I was again. But why didn't FF's Private browsing, or the built-in data wipe (cookies & cache) de-identify me? It can't see it having been advanced fingerprinting, or it would have seen through me wiping the virtualization layer.

Thank you!

Can I revert to the previous version of Firefox pre-this update - I find this GUI very difficult to manage. Everything comes up too large - and websites I'm accustomed to operating on are totally reorganized and have become hard to use.
