Hi, I've tried enabling Java Script but I must have chosen one of Firefox's browser extensions that is blocking it. I just don't know which one. How do I see those and make changes?

Thanks

How do you access Mozilla VPN after you have logged into firefox account - it only shows how to download and I have already downloaded it. I simply want to turn on the VPN and select the location but no instructions are available for this or at least the instructions are not clear.

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!

After Firefox updated, I can no longer access www.apple.com. This is the error I get now:

Blocked by X-Frame-Options Policy

An error occurred during a connection to idmsa.apple.com.

Firefox prevented this page from loading in this context because the page has an X-Frame-Options policy that disallows it.

Can anyone tell me how to fix this issue as soon as possible. Thank You.

Hi there, I would like to “generally accept all cookies” for future surfing through the internet. I found this description (see below), but it doesn’t seem to work (help might me older before latest browser updates), could someone tell me how to set Firefox to accept all cookies? Thank you.

1. Click the Tools menu from the top toolbar. 2. Choose Options. 3. Click the Privacy tab. 4. Under "History" select "Use custom settings for history" from the drop-down menu beside "Firefox will." 5. Ensure that the checkboxes for "Accept cookies from sites" and "Accept third-party cookies" are both checked. 6. Click OK.

We run Firefox on all our clerk computers at the public library where I work. Since the most recent update, our online circulation website which we use to check out books, receives a pop-up blocked message every time we try to print a hold receipt for an item. The website has always been added as an exception to our pop-up blockers, and until just after the most recent update, the blocker had no problem allowing the website through. Now it does. I have tried clearing the browser caches, removing and adding the website to the exceptions list again, and restarting the browser, as well as adding different variations of the website to the exceptions list. In the end, we just had to turn the pop-up blockers off. I searched online for anyone else who had this issue, but the ones I found dated back to 2014-2015, and the solution they came up with no longer seems to exist in the Firefox settings. So I'm hoping to find an answer here! Thanks.

So I need to search up certain websites and etc. But it tells me this website is restricted and when i turn safe-search off it goes back on again. If you can i need a solution for this I need a more simple way.

I was using Mozilla version 79.0.0 on Windows 7. I was using Mozilla since I purchased desktop, found no issue. I install retail POS software, since then not able to use Firefox. As soon I tried to open a website PR_END_OF_FILE_ERROR is displayed. I was also using Anydesk for remote troubleshooting of software. I uninstalled it, but problem is unsolved. I checked for proxy settings, nothing there. Refreshed Firefox, there is no Firefox profile created. I am not using any third party software for security. Windows defender is active. Any solution so that I can access web pages?

I can not delete my cache, cookies, browsing history, although I am in private/Strict mode. I have not had this issue before. I have tried everything except refresh Firefox option. What is the reason this is occurring and how do I resolve?

Hello,

I would like to ask you about error code that I got after last firefox upgrade to 78.3.1esr (64-bit). Everytime I go to certain websites I get this error message:

Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

Please, can someone advise about this? I do not see any known bug with this code. I did not have this problem before this upgrade.

Thank you, Martin

At the top of the about:preferences page, in a gray box, it says, "Your browser is being managed by your organization". Why? This is my home computer! How can I manage my own browser?

Hi,

I downloaded JDownloader yesterday. It forcefully installed some adware which became the default search engine, can't recall its name and Avast Antivirus. There was no option to uncheck them while installing. Since I didn't like JD at all so I uninstalled them all using Revo Uninstaller. Now while I searched something in the url bar few times that adware's page searched my keywords. I opened my settings and I got this message Your browser is being managed by your organization. PFA. This is my personal laptop connected to my personal wifi. Can I delete everything related to this junk without reinstalling FF? http://www.upl.co/uploads/14291556FF1580471775.jpg http://www.upl.co/uploads/161919FF-11580471781.jpg

How do I disable the warning screens that say "Warning: Potential Security Risk Ahead" when I visit sites on my home network (192.168.1.0/24)? Nothing I've tried seems to work. Thanks, Eric

No matter what I try based on internet searches, and on this forum, I can't get my browser to save any history. After I close the closer at end of day, it erases everything. I even created a new profile.... no good. Uninstalled and re-installed.... no good. Places integrity checker says the database is sane. I checked my system care software and disabled any privacy sweeps months ago. My older (a few years back) firefox used to save everything....
