Fórum podpory Firefox

If I open a website with Firefox then close browser and go to open another site on my desktop, Firefox says " Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window". If I hit the close tab, the new site opens. I cannot find any other instances of Firefox running when it says this. Other browsers, Chrome etc. do not exhibit this behaviour. Any ideas ?

This is really noticeable on some forums. The edge of text font turns slightly blurry (so the text camouflages a bit into the background), and when you click on the text, it disappears magically?

If I disable hardware aceleration to fix it, YouTube videos have horizontal lines in dark content, so it's not a solution.

Ok, as with everyone else my extensions quit working. My problem is have very limited bandwidth and just can't do updates for any software, just can't pay for it.

So how do I fix my extensions as mozilla has rolled out fix in a full update. This is not something I can do unless they are going to pay for it lol...

I just want my old firefox and extensions back lol... otherwise this is absolutely useless to me and might as well move on to waterfox or another browser, which is sad as I have been with firefox since beginning.

Why is it that one can loyally use a product and yet have the manufacturers hostile to your use ? Is Mozilla looking for money ? I would be glad to send money. My impression is that Mozilla simply is biding its time in order to super monetize the users. Prove to me I am wrong.

LS, My firefox version 66.0.2(64bit)run smootly in linux mint. The plugins for open h264 and Widevine are always activate. But the browser can not play the stream/ live for the website https://www.npostart.nl/live/npo-1. It shows the following message : Unfortunately, this program cannot be played in this browser. 22

Could You please help me ? With kind regards, Shari

Something that I think first began happening in the last 4-6 months. I can fix it by doing the Firefox "refresh/restart" but it keeps coming back. I had to do a refresh on March 10th and now I'm having the same problem again. Basically it's unable to download anything. Email attachments, files from a website. A pdf from a facebook chat log. Firefox acts just like it does when you normally go to download a file. Brief pause, some activity in the bottom left corner. Everything appears exactly right except instead of that little extra window popping up to confirm how you want to save it or where. That window never pops up and nothing happens. No files show up in my download history or default download locations. I only use 3 add ons. Firefox Lightbeam, Flagfox and noscript. But even if I disable all of them and restart my browser the problem persists. So basically I'm opening up other browsers and copy pasting the URL's into them to quickly download stuff because my preferred browser keeps losing the ability to download things :/ and it's annoying to keep doing the restart option and toggle the few menu settings/background I have back on.

Firefox opens fine and works fine. When I close it I get error messages. Event Viewer says the faulting application path is C:\Program Files (x86)\Mozilla Firefox\pingsender.exe, and the faulting module path is C:\Program Files (x86)\Mozilla Firefox\ucrtbase.DLL. The same module is causing faults in other programs I use.

I was not able to join my firefox on this computer to my firefox account. Isn't the sync password the same as the firefox account password. So the question is when I first start my firefox it asks for a password and the same when I want to see a password I have already stored. The strange thing is it states that it is the wrong password when I choose to login in to my firefox account. So now I am concerned because I received this email on April 1st and thought this was suspicious.

I received this email (also see image attached): From: Firefox Account Team <Mozilla@e.mozilla.org> Subject: Make the most of your Firefox

Usually upgrades are automatic with a progress bar showing completion... I don't ever recall a Firefox Upgrade in the format:

"Firefox would like to make permanent changes to your Hard Drive" [.sic]

I've had some Malware issues lately so I am suspicious of this unfamiliar format.

Thank You for your assistance with this matter...

Where am I to look or expect your response?? Through my Email Address would be just fine.

I followed these instructions:

In Firefox browser, type about:profiles in url bar. Under the profile that is in use. Click Open Folder on the Root Directory row. If that folder does not have a chrome folder, create a folder, name it chrome. In the chrome folder, create a file named userChrome.css

Then I put in the code, but nothing has changed.

Here's the code. If someone can look at it for me, that would be great. I didn't make it, but it seems to work for everyone else who uses it.

Hello

Since I'm working with a lot of B2B solutions that provide XML or JSON I have used this customer setting in Firefox:

network.http.accept.default;text/html;q=0.9,application/xhtml+xml;q=0.8,application/json;q=0.7,application/xml;q=0.6,*/*;q=0.5

In the inspector under teh network tab I see FF is sending this: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

I'm using FF66.0.2 and this has been working properly before. I can see that the default was changed in release notes, but the documentation still states that one can set this. Why doesn't it work?

I've tried this in safe mode as well. No change.

Web page blinks with many black blocks when using 3D street view maps. The website is https://map.baidu.com, and sometimes the browser may get crashed. This problem happens many times from the series updates of Firefox. Below is the debug info: {

Youtube video pages load, but the video does not buffer. Works on other browsers though. I tried solutions suggested online. Didn't work.

Version: 66.0.2 (64-bit) OS: macOS Mojave v10.14.4

when I opened firefox it tells me that it is not the default browser...ok...when I select make it my browser a screen then comes up with a table and selections for extensions...I don't recall ever seeing that and I was given a chance to select one or more or all but really don't know what this is all about anyway. A little help from you pro's would be nice and thanks!

Hi,

Not long ago my firefox on my laptop crashed and i could not get my old profile back and running again, so i decided to fully reinstall firefox from scratch on the laptop. Most of the addons and bookmarks were re-added due to the logged in profile.

Long story short, i want to prevent that i cannot access my profile anymore after a crash so i want to automatically backup the profile folder to a different folder (like a cloud folder for example). I have a FreeFileSync automatic backup setup but it requires to constantly run, it fills up my bin for all the files that keeps being updated by firefox and some file could not be backed up when firefox is open.

So i found symbolic links were you sort of make shortcuts to files and have the actual files in a different folder location. Can this be done with the firefox profile folder or will this screw up the profile?

Alternatively if the above can't be done, is there a way to move the firefox folder to a cloud based folder (for example dropbox) without any re setting things up? So when firefox is updating files within the folder it instantly gets backed up to the cloud?

Thanks in advance
