Firefox Support Forum

I have just installed Firefox 57 (Quantum) 64 bit on my PC and my Laptop (both Windows 10 (1709)).

On both my machines, Quantum displays pages appallingly slowly and often freezes, when no tabs or the settings menu can be selected and nothing else produces a response.

I cannot believe that this software has been properly tested on users' machines at their homes - its deficiencies would have been blindingly obvious. Their is clearly a huge problem here.

I was so looking forward to returning to Firefox but it is a complete disaster.

Please find a fix soon or I will have to uninstall Firefox, maybe permanently. It is useless to me in its present state.

How do I totally remove Shockwave Flash 15.0.0152. Using Ubuntu 12.04, FF 32.0.3. It seems that I have Shockwave Flash 11.2.202.406 installed also...How ???. When I disable SWF 15.xxx, it disables SWF 11.xxx also.

This was happening before I installed Chrome browser. Chrome is the only way I can use my computer without throwing thing about the room.

When I enable SWF 11.xxx, and leave SWF 15.xxx disabled, SWF turns on SWF 15.xxx. Seems these two versions are screwing up everything on my computer. Can't watch videos, FF goes gray screen and stuck, for 30 seconds, then recovers, then goes gray screen, then a message comes up "bad script -- Stop?", etc.,etc.

Lately when I am using T-bird email the screen goes gray and stops working.

Please help

Thanks SB

The audio on videos from YouTube/Facebook/Twitter/any website which allows video/audio play, is cracking. Mostly happens when there are multiple tabs open. What can I do? Also, I have tried doing a full uninstall and installing again, continues with the same problem. This did not used to happen before.

I am getting "error while downloading" while trying to install add ons, after having reinstalled, the add ons page now appears very basic with broken images but the navigation bar(ADD-Ons, Extensions, Plugins etc.) is'nt affected. What should I do?(And what is wrong?)

Thanks,

Ray

I think this is really a feature request, but I didn't see a forum for that. I used to use firefox almost exclusively, but switched to chrome when I started freelancing for a couple of different companies -- the identities feature of chrome really helps me keep my sanity by having a unique identity for each company. However, an issue has recently developed with chrome that made me switch back to firefox. The profiles feature in firefox seems to have gotten a lot better since I made the first switch, and I'm pretty happy with how it works ... with one exception:

With firefox, clicking on a link in a different application always opens in the default profile. With Chrome, it would always open in the browser window that was most recently active. This is a very intuitive behavior, as whatever I am doing in the other application (e.g. thunderbird, evernote, skype) is almost always related to whichever browser window I had opened last.

Any chance of this getting implemented? Or maybe there's already a way to do this? I found the following related topics, but neither helped with this question:

Suddenly while browsing, I got a bar notification saying that some of my addons had been disabled because they were unsupported. Clicking the button took me to a page that showed no addons, but linked to a page for Legacy Addons in which I found 25 of my addons (That's literally all but 2) have been marked as "not verified for use in Firefox" and disabled, despite literally all of them working mere seconds again and a large majority of them being obtained directly from Mozilla's official addon website! Firefox didn't even receive an update or anything, they just all randomly got flagged out of nowhere for no reason. Why are all of my addons suddenly marked as unverified and disabled, and how can I enable them all again?

I know that firefox once put the tabs on top, but I had that fixed with setting in "about:config" the value for "browser.tabs.onTop" to "false". Now, after upgrading Firefox to v.29 this entry is still set to the false value, however, I can't get the tabs below the adressbar (which is super annoying). Any ideas how to resolve this?

Sorry guys, i am disgusted with this upgrade. 29 does not seem like a good ui update at all. The menu bar looks really bad and so does the tab. Furthermore this does not solve my other tab issue i have either in another question i have asked.

How can i revert back to my last version with all my tabs/windows/history restored? I will do a system restore if i have to and then cancel all automatic updates. I honestly dont care if it gives me a bigger security risk.

After Firefox update to 49.0.2 i have problems with videos on sites like: http://www.cc.com/video-clips/07m87l/the-daily-show-with-trevor-noah-donald-trump-hints-at-a-not-so-peaceful-transfer-of-power or http://time.com/4514971/iphone-7-worlds-tallest-building/

There is only sound, no picture, just grey/black background. Downgrading to 48.0.2 helped, but on this version Netflix videos aren't working.

Hello!

So, I was working on a new blog on which I'm using the Rubik font from Google fonts.

Everything was fine for several days, but today, after working for some time on it, the font just got messed up randomly (see attached image).

I added the font on a different, testing site and it shows messed up there as well, so it's not something website related.

Now, the shocking part is that it gets messed up only on Mozilla and only on the Mozilla browser that's on my Desktop PC.

I asked a friend to check it out and I also checked it out on my laptop, and the font is fine on other Mozilla browsers, as well as other browsers.

Other fonts from other websites are fine as well.

What troubleshooting I performed:

- Checked the font with Inspect Element, as it's shown here: https://developer.mozilla.org/en-US/docs/Tools/Page_Inspector/How_to/Edit_fonts and the font is set up correctly;

- Deleted the whole history since the beginning of time (cookies, cache, everything);

- Closed and opened Firefox again;

- Opened Mozilla in Safe Mode (hardware acceleration is disabled by default in safe mode);

- Restarted my PC;

- Uninstalled Mozilla as it shows here - https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer. Deleted the profile folder and everything.

- Installed a fresh copy again with no add-ons, no nothing.

Nothing worked. That font is still messed up on Mozilla, on this PC.

It doesn't make any sense, especially since it went nuts randomly without a particular reason.

Does anyone have an idea of what could be the problem and how to fix it?

Any help would be appreciated!

Thanks!

I open up Mozilla to my saved tabs and a box pops up stating Nightly needs to restart to update. I usually have my pc on "sleep" but wonder if I can just do one big update and get it over with?

Hello Techies, First meet my system... Linux 32bits (Lubuntu), provided with: Lightspark, an SWF player, and all what Linux comes with.

I try to connect to a site, a radio station one, and Ff tells me a web page is slowing down the load process. Wait? Stop? Waiting is useless because the page never loads. Stopping leads to the site (simple http, without "s") but many parts of it do not respond. In other parts of the site Adobe Flash Player is mandatory to access the content. As you can imagine my system is not provided with Adobe and I guess this is why Ff warns me and can't access the site. I'm not installing Adobe, I don't even know if it is possible, and safe! How can I fix this? To me I should overstep Adobe, installing to the system something similar that the site can "like". Any suggestion? If you need it I can give the exact URL of the site. Many thanks for your educated answer!

I am unable to access my GlobeInvestor Streaming Quotes (http://finserv.globeinvestor.com/fcclient8/mainframe.htm) via GlobeInvestorGold.com. When I click on the "Tracker" link on the GlobeInvestor Gold website to access my streaming quotes, I get a pop up with an error stating:

I have restarted Firefox numerous times. I have reset Firefox. I have re-installed Java a few times and I have also updated all plugins. I am running Firefox on my MacBook Pro. If you could provide any assistance, I would greatly appreciate it. Thank you so much in advance.

I have upgraded to Firefox v28. I want to save a mp3 file for playing later like previous versions of Firefox. When I click the file it starts playing and does not give me the option to save the file. In Options the 'application' settings for file type MP3 is set to 'save file'. The quicktime plugin is disabled. The media.windows-media-foundation.enabled is set to false in about:config How can I restore Firefox behavior to be like the old versions Thanks

Hello, youtube videos are freezing for no reason, mostly after 14 seconds and never start playing again. I need to refresh page often more than 1 time to get video load. I'm using latest flashplayer, and I guess firefox (32.0.2) too couse I have automatical updates. For addons I use adblockplus, youtube high definition 32.0 and proxymate.

For plugins i use adobe acrobat 11.0.9.29, Java se7 u67 10.67.2.1, pando web plugin 1.0.0.1, shockwave flash 15.0.0.152. 

I have read about adblock plus can couse this problem but when I disable it, nothing changes. Also i have reinstalled flash player, firefox used Ccleaner to clear all cookies, history, etc. and it doesnt help. I have tried Google chrom with same addons and it works, but i dont want to use Google chrom so i ask you what to do.

Firefox shows that my Adobe Reader needs to be updated to version 11.0.84 and when I try to do the Adobe Reader update, it tells me I already have it.

I also did a refresh of Firefox and I still have the same problem. I am using Windows XP SP3. I do not know what to do. Thank you. Please tell me what I should do next.

Thank you.

Although the Norton Toolbar now appears in 42.0, the Identity Safe feature does not work with. Firefox does not provide the same level of browsing assistance that Norton's Identity Safe does, and using Firefox without the Identity Safe requires many additional keystrokes and much additional wasted time. Norton assures me that the Identity Safe should be compatible, and it works fine in Internet Explorer. Norton claims that the Firefox "checkers" are still vetting the program compatibility issues, but how long will this process take? Using Firefox without the Identity Safe is so cumbersome and tedious that I may have to try Google Chrome or go back to Internet Explorer, although I have used Firefox ever since it first came out. Please don't force me to switch. Thank you.

I received a notice to update Firefox, then it said cannot update due to add-ons. I don't know what they are & are they safe. Also, Firefox keeps crashing? Thanks for your help!!!!! Connie
