When receiving the following messages when accessing a specific URL.

Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to xyz. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Then clicking on the Advanced... button at the bottom of the popup window.

And then clicking on the Accept the Risk and Continue button.

My question is does Firefox make any changes to Internet Options or anywhere else, including within Firefox to change configurations of any type when the Accept the Risk and Continue button is clicked on?

Thank you!

Hi,

Firefox updated today on my Mac to the latest version. I want to go back to the version I was using before, as in yesterday. (It was first installed on 9th April 2019, but I don't remember if it was updated at any time before today or not - so, not sure which version I was using yesterday).

How do I get back to yesterday's version without losing my bookmarks etc? This new version doesn't give me the option of having Google Chrome when I open each new tab - only Firefox or a blank page, which I don't want. Also, the version I was using up until yesterday (and this morning, actually) was much easier for me to see on-screen; at least the tabs look different on this new version.

Any help would be much appreciated.

Many thanks in advance.

Firefox version 94.0.2 isn't supporting Netflix streaming, on my pc windows 10. Always worked, but stopped this evening. Google Chrome works, but not Firefox. Firefox is my browser of choice. Can you help me.

My email is through Century Link. When I go to centurylink.net, click on email, it won't load. If I turn off the HTTPS requirement, it will ask for my login/password, but the emails won't load, just a white screen. I have no trouble getting emails using other browsers.

Hello, John aka Beer Gutt here.

A while ago (about three months), I moved my hard drive to a new PC with better parts. It has a better mother board, a better graphics card and twice the RAM. Anyway, since then Firefox hasn't worked the same. When i open Firefox, there will be random pieces of letters or words on a webpage just gone, making a lot of them impossible to browse because I can't read half of the the new Alien dialect on the screen. Some websites have been better than others, but its gotten to the point where some web pages (Like YouTube or Reddit for example.) will just be a mess of random de fragmented lime green blocks that completely corrupt the page and will shift, move and appear at random covering up text as I scroll down. Videos will play just fine, it's the rest of the site that's effed up. Also on YouTube videos, where the timer for the video is located, some of the numbers just won't show up. Like it will count down fine but won't display certain numbers in the timer. Funny thing is, is that this doesn't just affect the websites, but the browser itself. For example, hovering my mouse over different tabs will highlight them and show me the preview text of the tab. All that is good until I move over to a different tab and voila, the text is gone, and then suddenly all the other tabs are either blank or just missing random letters and numbers in the tab. This is only happening in Firefox btw. No other app on my PC is doing this. I've tried refreshing Firefox about six times now, I've uninstalled it three times in an attempt to fix the issue along with restarting my PC multiple times... All of that, and I find out yesterday that it works perfectly when in "Troubleshoot/Safe mode", and only when in Troubleshoot/Safe mode. I have no idea what is causing the issue... *PePeLaugh* 

 See, I would use another browser but I've been using Mozilla for 8-9 years and would like to avoid the hassle of moving everything to a new browser... I would VERY much appreciate any help at all.

 I'm running 64-bit windows 8.1 on the latest updates and my PC specs are roughly as follows below. I look forward to a response...

MSi 970 Gaming Motherboard

AMD FX(tm) 8350 Eight-Core Processor 4.00 GHz

24 gigs of RAM

Asus Radeon R9 380 Graphics card

This has happened on several of my computers. Upgrading from some version of FF80 to some version of FF90 results in gibberish text.

What Mac OS system fonts does Firefox require? I somehow got this fixed on one system, but many monthds ago, so I don't know what actually worked. I have cleaned font caches, etc. but cannot get it fixed on the latest so far. Settings are Latin, normal fonts like Georgia or Verdana.

I have done all the recommended solutions including Refreshing Firefox. Youtube still will not run. I just get the pic and the rotating arrow. Have to copy the url and open any other browser and paste. Mac OS vers. 11.6.1 Firefox vers. 94.0.2 64bit

Lately (as of which version, I'm not sure), I've been noticing that if I enter a URL in the address bar of a tab that already has a page open, instead of going to the new URL I entered, Firefox will refresh the current page instead. This happens A LOT and is pretty annoying. Wondering if this happens to anyone else.

Hello! I am using Firefox ESR in Linux Mint 18.3 32-bit. For convenience, a few years ago I've created a start menu (main menu) shortcut to quickly open a Private Browsing window. Before the recent switch from ESR branch 78 to 91 this shortcut was working as intended, but now, it opens a Private Browsing window and a regular browsing window. Here, I've made a short video about this issue that should help to better explain everything https://youtu.be/ccioyh0gJxA https://youtu.be/ccioyh0gJxA To some, this might seem like a non-issue, but I'd like to have a shortcut that would allow me to launch a Private Browsing window and a Private Browsing window alone.

Tell me please how to "unplug or eject hardware" in Firefox. I have gotten a Verbatim External Slimline CD Writer that directs me to find this option in the Windows taskbar. But I use Firefox as my browser and don't know where to execute this on the Firefox taskbar.

It took years to perfect my userchrome to make FF look exactly how I want. Once 91+ came out it wasn't even a question of fixing the floating tabs and condensing the height and menu spacing (though I tried all of it) but my own codes stopped working properly - I had code to set the background colour of menus/bookmark menus and when I upgrade they were the right colour but with thick white borders around them. This was more important to me than the floating tabs and I immediately downgraded to 90 where I've stayed. Can anyone help me figure out how to get MY codes to work with 91+ and/or to work together with the other fixes out there (tabs, condensed menus etc)??

Below is how my userchrome looks and attached is how my current set up looks. ANY advice is appreciated. THANK YOU.

Hello, Which version of Firefox supports, fire path and firebug extensions? In my Laptop Firefox version 94.0 is installed. What should I do to install fire path and firebug extensions for my automation testing?

Thank you

The "restore previous session" option is no longer in the History section. All I can restore is individual pages. I often have a lot of tabs open, and twice now just in the last few weeks, I've lost the whole lot. One of those times I had closed Firefox, the other time it closed for no apparent reason.

I don't know how this started but I'd be really grateful for help. Firefox is virtually unusable now. (See attached photo.)

And BTW:

I can't even see how this could be helpful to anyone but maybw it's to do with specific sight problems some people have? Why doesn't something show up to say "You are in xxx mode which makes your screen purple. The purpse of this function is xxx To return to normal mode do yyy."?

I think Firefox staff, like most people in IT, really don't understand that non-techies like me just want the thing to work! No, I don't want to spend hours sorting it out!

Whenever I click the PiP floating icon on video-hosting sites such as YouTube, the PiP window pops up but does not stay on top. It is immediately hidden by other windows. I always need to open the window menu and enable "Always on Top". Shouldn't this be enabled by default? Is there anything I can do to make it enable by default?

For reference, I'm using GNOME 41.1 on Manjaro Linux.
