Firefox Support Forum

I have to use version 51 so that I can use Java to open Oracle (I refuse to use IE). I have checked the box to never check for updates, Mozilla updated anyway. I deleted everything I could find on my computer Mozilla related, re-installed version 51, checked the box to not update and checked daily to make sure that there were no pending updates. I ran it for about a week just fine, but then it crashed and when it restarted, it was on version 53. I deleted everything Mozilla again, re-installed v51, told it not to install the sneaky background service, checked the never update box, went into the about:config and made sure the setting really said not to update, then went into the prefs.js file to triple check that it really really wouldn't be set to sneak in an update, and then went and double checked that the sneaky background service wasn't installed, then made sure it didn't have any pending updates anywhere. Ran it fine for a day, it crashed, and when I restarted it, surprise, surprise I'm on v54. It shouldn't be this hard to just stay on the version I want to use. What in God's name do I have to do to keep it from updating? Does Mozilla just ignore what the user actually tells it to do and does what it wants anyway or is my version of Mozilla just trying to start the Skynet revolution? I'm pretty close to just writing a vb script to just delete everything Mozilla off my computer and re-install v51 it everyday at midnight so I can just not have to deal with it anymore, but I figured I'd ask for help here first. If I can't get help here, I'll probably just go under my desk and cry while eating glue and rocking back and forth until they either fire me or have me committed.

How can i please run two copies of firefox at the same time, it worked ok until update to 50.1, by adding this to the icon target box. 1. -no-remote -P Default 2. -no-remote -P Username

But now seems to not work anymore.

Many Thanks

In short, I want to be able to bypass certificate warnings.

Yes, I've seen this: https://support.mozilla.org/en-US/questions/1169632 "When there is HSTS(HTTPS Strict Transport Security) set on the server, you cannot add a exception"

In less short, my case (because one needs to always justify one's methods), I set up a subdomain on a separate IP/host and I'm trying to test some project for which I use a webpage as a small visible part. However, the domain uses HSTS (HSTS == very nice).

However, I'm just casually testing something using a subdomain (or even a fake domain, or a real domain pointing to a new server being prepared, maybe using /etc/hosts) pointing to an external or internal IP on some old computer on my LAN or even on my own computer. And that's not possible anymore.

People should always have the option to bypass a warning, and I'm all for the warnings. If anything, there shouldn't have been a box with the option "always remember" ticked by default. There are other cases where this can be useful, some we don't even know yet.

Hi!

Since an FF update, I receive more and more push notification popups ('Would you like to receive notifications...'). It asks to en/disable it for a specific website but than it comes on another one. I don't want this feature and I never have asked for it.

How can I disable this pop up once and forever? I tried dom.webnotifications.serviceworker.enabled to false and dom.webnotifications.enabled to false, but the notification popups contnue to disturb me. I simply don't want to be asked.

Hi!

Since firefox updated a couple of days ago, I've had nothing but issues with my flash-based games. Tonight I have an error message on one game I play:

Context3D not available! Possible reasons: wrong wmode or missing device support.

How do I solve this?

Thank you!

Karen

When I am on Facebook it is sluggish and freezes sometimes to the point where I have to kill the browser in task manager. it seems to be only on Facebook and only on one account. My personal account stalls and freezes up, yet my daughters on the exact same PC using Firefox doesn't. I have tried several on line trouble shooting links and nothing helps. Facebook works fine in internet explorer/edge, Chrome, and etc., but it is a pain to have to jump from one browser to the other. This issue just started about one week ago.

I had a list of Add-ons on my Firefox running on XP. There were issues with the XP system that forced me to wipe the Hard drive and do a clean install of XP. Now that it is fully running again, I have installed Firefox. PROBLEM... I do not remember all the Add-ons and there settings. I did backup my previous system including c:\program files on another hard drive.

1) Can you point to where the Firefox info is stored? 2) Is there a way to copy the old file or can you read it and supply the Add-on names?

Thanks.

Two error messages randomly pop-up while browsing or opening a new tab

The first messages show's this.. ```Firefox has detected that the server is redirecting the request for this address in a way that will never complete.``` And the other.. ```Firefox doesn’t know how to open this address, because one of the following protocols (mega) isn’t associated with any program or is not allowed in this context.```

Is there a way to have multiple languages packs activated at the same time?

I'm from Sweden so I'm writing a lot in my language of course but i also write in english on other sites like youtube. Can i have multiple languages packs activated at the same time so that i don't have to choose what language i I'm going to write in because i really need the spelling correcting function in the language pack because I cant spell :)

Firefox downloads pdf automatically - this is maddening! It needs to open the page where the pdf is, leaving me the choice to download or not. Can I change setting so that Firefox either opens the page of opens the pdf? Many thanks

Every time i need to upload a file to a website, as soon as i click Browse to find the file, Firefox crashes. Using Chrome to do the same thing works fine. I have had this problem on several different websites.

My friend Matt has been using the current version of Firefox for quite some time on his Windows 10 Pro desktop that's up to date, but a couple weeks ago he installed the current Chrome because he has to use it at work and decided to see if he could get it to work like he wanted at home. Anyway, he decided he couldn't get it to behave like he wanted and went back to Firefox being the default browser and uninstalled Chrome.

Off and on since then, youtube clips have no picture, just a black screen. Audio plays fine. If he switches to Edge and pastes the url into that, it works fine in Edge. Not consistent on when it will have no video though. I remember over the years this being a problem sometimes and having to just keep on trying different solutions until we hit on the right one.

I did google clean uninstall of chrome and found some directories and registry entries to delete, but it still has the no video problems sometimes. I also tried deleting the youtube cookies and un-checking the box in firefox for use hardware acceleration when available. Still the same problem. It will do a few youtube cips fine and then no video again.

I'm going to start trying all the suggestions for this I find searching soon, but from what I've found so far, all the posts are from 2008-2014 or earlier. Anything Windows 10 specific or current Firefox (51.0.1 32-bit) I should try before the older stuff?

my icon home button is gone from the top when i go to a my favorite button to go to different places i can not go back home ther is no icon button i have to hit my x and log back in.

For some concise background, I'm a designer and need to work with a variety of typefaces. I had a lot in my font folder, for Windows 7, and cleared them all. Of course, there are some the system wouldn't let me delete since they're essential. Then, I installed the fonts I needed after. My font folder is ideal right now.

However, there's one small problem that's irritating me. On a variety of webpages, such as Yahoo Answers and Behance, there's a version of Helvetica or Helvetica Neue being displayed, either one of the thin or light fonts. See the attachments.

The funny thing is, I purposely deleted those fonts since I don't like them. As you can tell, the thin/light version is very hard to read and almost has no use. When I had those fonts, I still had this problem, so I'm not sure what to do. I also have this issue with Internet Explorer on the same pages. Firefox lets websites choose their own fonts, which obviously gets rid of the issue, but brings about a whole variety of new issues depending on each webpage that I won't bother explaining.

There is no way to download Windows 7's default fonts in 2017, to my knowledge. I've searched far and wide on the internet for a solution. I could ask Microsoft about this problem, but they'll likely just tell me to buy the latest version of Windows.

I'm running a 64-bit version of Windows 10 Pro. I just used Help | About Firefox to update. i was running a 64-bit version of Firefox. The update to 51.0.1 switched to a 32-bit version. Why did it switch from 64 to 32-bit version?

In Firefox 51.0.1 I have a problem with print (CTRL + P). Firefox runs on Windows 8 in a normal Windows account without administrator rights. If a printer is selected (network printer or pdf), the "printer error" window that says "There was a problem during printing." The printer prints a blank page or PDF document shows a blank page.

I have tried the following: 1. Print Setup Firefox reset 2. All printer settings from Firefox reset 3. Change the default font 4. Firefox refresh

After freshening up I could again print a Web page, but after changing options such as home in "https://www.google.nl" or adding extensions, it does not print again.

I have no problem with the printer or PDF printing in other browsers such as Google Chrome.
