Firefox Support Forum

Since the newest update, it is impossible to simply clear the cache, from the browser. When I click on the "Clear Now" button, it only reduces it by 1 or 1 megs at a time! Well, if I have 550 to clear, am I supposed to sit here all day, to do what used to take five seconds?

So, so far so good except for one thing with the update to Firefox 45. When I start the browser up, my whole screen hangs and freezes for a good 25 seconds. Anyone else having this problem? When it first happened I thought I'd be manually restart my computer as I couldn't even get into my task manager and the cursor was unmoveable.

Everytime I play a game, firefox decides to pop up about 20-30 pages of my homepage. How do I stop this? I scanned my computer for viruses and have adblocker and none of these work are contributing. Its been going on for 2 weeks now. If I'm not using firefox, it happens on Chrome as well.

When there is a live stream on Facebook, I cannot view it using Firefox, though I can hear it fine. I do not have any add-on's installed. I can see it fine in Internet Explorer and have reinstalled Adobe Flash just to see and still nothing.

After my upgrade to 45.0, whenever i try to do a search in the toolbar, I get the following error:

Your connection is not secure

The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.

When I click the "ADVANCED" button, I get the following:

www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

This was never an issue, until the upgrade.

Please advise, thanks,

Acer laptop, i5, W7x64. FF locks up so I have to close tabs & start again, sometimes get error report about the "Plug-in container has stopped working" or "There is still a version of FF running, you gotta close this first" even tho' I've closed FF, gone back to the OS & checked the Taskbar for running progs (no FF) then tried to restart FF. Sometimes I get a message about FF not being able to tell if I'm using the latest version (I am). Sometimes I just get a heap of blue script down the left of screen (not a JS prob - allow all this page). I have a very slow connection (hey, this is Australia, the Govt still thinks the internet is not important) so this only compounds the problem. What can I do?

Alright, so. My website uses google font 'Montserrat' and the latest firefox update breaks it. To be honest, I'm sick of having to rollback (see notes below) because all that happens is the damn thing updates again without my permission. It's driving me nuts.

It looks absolutely awful, it's super jagged and just looks nothing like it should.

I think I've isolate at least part of what the problem might be. The 'unicode' font choice in option > content > font & colours is not there. It's stuck on 'latin' and there's no option for unicode.

I have tried fresh installs and all that jazz. The settings are correct except what I mention above. The page is allowed to choose it's own fonts, etc.

I've troubleshoot this issue quite a few times and the only thing that's fixed it is taking an old version from my husbands computer and using that.

If anyone could help shed some light on this I'd be extremely grateful as my site looks stupid without the font rendering correctly!

So far, Facebook, Youtube and Vine aren't affected.

Yesterday, Firefox stopped playing GIFs (which are actually displayed as videos) on Twitter. I can see the play button and the "GIF" word on the corner, but then the image turns black and the following message appears: "This browser does not support video playback.".

I honestly have no clue how it started. One day it was working fine as usual, but then it happened. Refresh feature didn't solve the problem, and entering Safe Mode didn't work either. It seems it is a rare problem, since I can't find any solutions on the Internet and I tried asking if this was a known issue to Firefox account on Twitter, but I had no answer.

This is seriously annoying, but I noticed another browser, the Vivaldi, also has the same problem, but Google Chrome doesn't. This is really confusing. Can someone help me?

I have problem in pages which are using Java. They are really slow to use. Sometimes I have to click button twice to make it work. Example is a net game page: www.howrse.fi or www.howrse.(insert your countrycode here) .

FF has stopped restoring the session on bootup. If I quit FF using the menu before reboot, session restore still works automatically on bootup. If I shutdown/reboot without first quitting FF (my normal practice), I will always get the session restore dialog to manually pick a session to restore. Every reboot new seems to be treated as a browser crash. I see this on both WinXP and Win7. The Win7 is a new install so everything is fresh.

it's the same question mentioned in https://support.mozilla.org/ru/questions/1113128#question-reply but installin Frfx 45 didn't solve the problem as well as all your advices there once I made new profile and it worked ok, just until I've reinstalled FEBE 8 after this no shaman dance worked I've been installing and uninstalling flashplayer and frfxes of different versions completely with revo uninstaller - no use I've been killing every entry concerning in regystry, I've erased all folders attributed to Frfx - nothing helps btw FEBE 8 can't restore search plug-ins in Frfx 45 guys it's all very ugly and depressive

Hi All,

It may sound silly, but is there a description of all the options under Tabs? It seems that many versions ago, with the subject option checked, I could click on a bookmark and new webpage would open in a new Tab. This no longer happens. Has there been a change?

I must now right-click a bookmark (on bookmark bar) and select "open in new tab", or Ctrl-click on bookmark.

Is there a way to force open a new tab, by just clicking on bookmark?

Thanks.

last 3 day ago i setup windown.. but now i login my mozilla account not sync any data . like user name password url history,bookmark if possible how i get my data

When I try to view a pdf file that is attached to an email it opens a poor copy with word online, that can't be printed.

When I try and download the pdf file from the email attachment a dialog box ALWAYS pops up asking "what to do with this file?" The dialog already has my default reader selected and the "do this automatically for files like this from now on" box is checked.

Every time I try and download the dialog comes up.

I'm running windows 10, firefox 45.0.1, foxit reader 7.1.5.425. Emails are on outlook.

Why is getting an answer so difficult? I can't be the only one with this problem. I'm on CNN trying to watch the debate. I can watch with MS Explorer, but I'd rather not.

I don't want Mozilla starting in a private window to be the default, just an option. This used to work. I was presented with options, now I only get Mozilla, Unpin from taskbar, and close all windows. Using windows 10

Hi Guys,

I keep getting this rather annoying pop up which says "Stop running this script?" It goes on to say that a script on this page (presumably net page) is causing my web browser to run slowly. Furthermore, if it continues to run the computer may become unresponsive. As far as I can tell, nothing has slowed down but constant pop-ups is beginning to bug me. Are these pop-ups harmful? Do I really need to do anything anf most importantly, how do I get rid of them?

Thanks

Folks,

It isn't that I want to be difficult, but just now I am at wit's end trying to work out what is going on.

I have FF on two machine I use a lot. PC (Main desk top type) and my lappy which has "wide screen" 16:9 aspect rather than the usual 4:3.

Of late I have been using the lappy a lot and was confused why the screen was not as "friendly" as it used to be, or as I remember it. I put it down to me being forgetful and didn't worry too much, but then the other day I turned on the desk top and used FF there and WOW! Now I see the difference. See attached picture.

On my desktop the area in red is two lines "thick" (wide/what ever) and here it is only one.

Not too much of a problem, but I am totally at a loss how to make it like the desktop machine.

Also, though a WHOLE other problem, but while I am here: I can kind of guess that when a web page is "designed" fonts, sizes of fonts and stuff like that are chose to make it "look nice", but here, I am on THIS page, entering TEXT..........

As I am "old school" with things, and have adapted to the newer keyboards, though I really didn't know the OLDER style, I know there are some very specific keys which MUST be used in the right situations.

Example: Typewriters did not have the nubmers 1 and 0. Lower case L was used for the number 1, and the letter o was used for 0. I get that, and they ARE different things to the computer.

But I really dispise these fonts where lower case L, capitol i and the number 1 are SO SIMILAR that they can hardly be told apart. Though I have to admit, the 1 at least is different.

Here is an example:

IIIIIIIllllllllllIlIlIlIlIlIl

OK, there is a SUBTLE height difference.

I went into the options/content screen and set a different font. See second picture.

I am perplexed why there is a FONT SETTINGS option and when I set it, it is overwritten and this font is used.

Could someone explain to me where I am really going off the tracks?

(oh, and now I am stuck after adding the two pictures to where the "SUBMIT" button is.

Ah, found it! (See third picture) What can I say?
