I would like to be able to completely refresh all scripts, images and code (absolutely everything on the page) when I click refresh for a tab. I am a web designer and firefox often serves up old content, regardless of whether I manually empty the cache or click refresh multiple times on a page. I tried some chanegs in the config file too which I saw for earlier versions of firefox but they don't seem to have helped. Any suggestions similar to cmd-shift-r that force a complete refresh of a page would be very much appreciated. Even if there is a way to turn caching off completely so that surfing the web was slower that would be preferable to be able to test site updates correctly. I use firebug so if there is an option in there for forcing full refresh of pages that could also help. I am using the most current version of firefox (43.0.4). Thanks

Hi There,

As of today I seem to be having a strange issue with Firefox 31, I'm unsure as to when this problem began as I haven't developed on this project for around 2 weeks. I have a PHP Development server running on localhost port 8000 using the following command: "bin\php -S localhost:8000 -c php.ini" (without quotes)

Upon trying to connect to this server via Firefox I'm presented with "Firefox can't establish a connection to the server at 127.0.0.1:8000." the message adjusts to show "localhost:8000" when connecting via that method, I've tried running Firefox in Safe Mode, reinstalling Firefox and also changing the network settings to "No Proxy" from "Using system proxy settings".

I'm able to connect through Chrome, IE and also by running a cURL command.

Just recently (I believe on Oct 30) I have been encountering this problem while trying to log into the Rooster Teeth web site. I have tried clearing cookies and cache multiple times to no effect, and the help page suggestion for the workaround of clicking "Or you can add an exception..." doesn't work because that button does not appear on the warning page anymore. I am only getting this warning error when trying to log into ( http://roosterteeth.com/home.php ) and only while trying to log in, it doesn't pop up for anything else on the site or any other site that I've gone to. Any help on fixing this problem would be greatly appreciated.

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

How to hide the address/URL bar again ?

Hello all,

I run a bunch of web applets locally on my computer for personal use only (http://localhost/...), and until recently I could successfully launch FF using window.open(...) with the new window NOT showing the address bar (because it takes space and looks ugly within the applet, so I want to avoid it at all cost).

I believe this changed with FF 76 (I now run v. 76.0.1 64-bit on a Windows10 based computer), anyway at this point it seems impossible to NOT have the address bar show up in a FF window. :-/

To be clear : I have searched for a solution in this forum and elsewhere, found the solution to another new problem with FF ("megabar"), also seen the trick to hide the url in the address bar - but this is not what I'm looking for : I just want to *get rid of the address bar*, period.

Thanxx in advance for any help with this issue (surprised noone else seems to complain about this). :)

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

I have open half a dozen or so tabs related to one subject. I would like to put them all into one "super tab", such that only the super tab shows as an open tab. Then, by clicking on that tab, it would show the tabs within it, any one or more of which could be selected. Is this possible, and if so how is it done? Perhaps there's an add-on or extension that would do this.

I have already created a multi-tab bookmark that sorta, maybe accomplishes the same thing. But it's not as convenient as what I envision as described above.

Thanks for any advice or words of wisdom.

The message comes often some seconds after a new site or adress was opened but not everytime. In earlier versions it was quite rare but now it comes almost with every change. The solution I have found in the web

    1- In the Firefox Address Bar, type in "About:config"
   2 - Click on button to continue
   3 - In search bar, type in "Websocket"
   4 - Set network.websocket.enabled to false 

worked just for the first day. The parameter is still set to false, but it does not help any more. I have the german message but the problem seems to be general and was not solved up to now.

I think that I'm pretty much done with FireFox and this may be the last straw. When I try to open Firefox, I'm getting the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I tried all of the things that I could find on the web. There's no process running, so can't kill it via "Force Quit". I tried deleting the .parentlock file, using terminal, which seemed to be an approach that others suggested, but there was no such file. So, I'm stuck. Before I just completely give up on FF and move to Chrome, does anybody have any other ideas that might work?
