I seem to be encountering various problems since the update to 73, the main one is the profile folder, I dislike the default location so have previously just put my preferred location in appdata\roaming\mozila\profiles.ini but 73 regularly ignores this and puts a basic profile in the default location and alters profile.ini. Using the profile manager does not get any better results. I am also having problems with the home page, I have set a custom page but 73 often resets this to a blank page or sometimes the default home page. I have had to resort to a 'portable' version as 73 constantly resetting things was getting so annoying but the portable does not work well as a default browser.

Firefox does not launch on my Mac at all. After installing, everything was ok for a few days (I've installed some extensions like Disconnect, Adblock, ublock), and suddenly the browser stopped launching. I was trying to re-install it again but it did not work. Also, was trying to check hidden files and folders but nothing except some files in the MacOc content folder ( see att.). Could you please advise me on this issue hot to resolve it? Thank you in advance!

We are using firefox as default browser. We have an application which require user authentication. Here we are trying to authenticate our user using client certificate which is already installed on windows user trust store in Personal and a self signed root certificate in Trusted Authorities. Firefox is not able to give popup to select a client certificate.

I also tried https://support.mozilla.org/en-US/kb/how-disable-enterprise-roots-preference but no luck.

The feature that stops videos from automatically playing doesn't work on the News Website Independent. Adding it to list of Websites to stop Playback doesn't work either.

On macOS 10.15.4 with Firefox Developer Edition 73.0b5, when I open a new Firefox window, instead of opening to my home page (blank), it chooses some site from my history (perhaps the last separate window that was closed?), and I can't modify the URL bar. I can still navigate via history and bookmarks, however.

After installing a new bios update to my motherboard , firefox tabs constantly crash and then minutes later the whole software crashes and closes itself. Have tried re-installing already, and I have unticked the hardware acceleration in the settings.

Some of my add-ons were corrupted or become unavailable after 74.0.1 update, WHY??? I use a lot (indispensable to me!) the addon Save Page WE and now is not available despite it is listed and appear as active in addons list. Also, some addons started to behave weird, like Adguard which now show a annoying setup window on each new Firefox load. Also OneTab is not loading, the icon still in tool bar but it does nothing. Please, what happens? I know there are improves in each new update, but at what price??? Please stop that!

I've used Firefox's protection settings on strict, until I realized how much it increases my CPU usage. This was during some experimenting after I've noticed that my Task Manager states 70%; a majority of it being used by the browser's engine (I kept it on standard and installed uBlock Origin since then).

What's with that?

Roboform is up-to-date and works on all my other joomla and wordpress sites as normal Roboform works on Chrome, It also works manually on Firefox entering username & password. And of course it worked until the upgrade. The same behaviour happens on Firefox developer edition

As above- upload test shows about the same amount higher than Edge. This has been occurring for around 3 months since I upraded to fibre broadband. Before the upgrade FF as always faster on both down and upload speeds. Immediately afer the upgrade Edge ad FF were the same This was so for about 3-4 week after the uprade, then the FF speed fell. There have been several updates to FF and I have tried reinstalling FF and various other changes to settings all to no avail.

I am using Windows 10 latest versions on two seperate laptops,one being a Toshiba ( Windows 10 Pro) the other an ASUS (Windows 10 Home). Both have this problem. I am using the Ookla Speedtest.net and the Talktalk speedest (also supplied by Ookla) and with the same results. The problem is the same with wifi as with ethernet. I am in the UK. I thought it might be the router, but why the difference between browsers and why after a few weeks and not immediately after the upgrade? Appreciate any sggestions, thank you in advance.

I downloaded the add-on from here: https://addons.mozilla.org/en-US/firefox/addon/marathi-dictionary/

It works correctly only for the words those are there in the .dic file. But does not read the affix file and therefore I do not get quality options on right click. This was working as expected before the last update of firefox.

I have a php site that is using a MySQL dB and has a few JavaScript1.2 elements on the page. After updating from Firefox 68 to 74 some of the pages have stopped loading. It starts to connect and I can see the queries running on the database but Firefox gives up before the queries return any values. If I click on a link again after it stops loading it sometimes goes through and finishes loading or downloads a generated file on the second or third try. the amount of time before it gives up seems to vary each time.

I have tried disabling JavaScript to see if that has any effect but it didn’t help. as well as seeing if it was a variable that changed in about:config but haven’t found anything that has made a difference.

I have other computers running older versions and they all load the site like they should and it also works in chromes latest version, safari and IE.

If anyone has any ideas on what could be wrong it would be much appreciated. I have been stuck on this for about a week now with no luck.

I can't access my TP-Link router from Linux, I got SEC_ERROR_BAD_SIGNATURE and no options to add an exception, since some versions ago. I can using another browser on Linux and with Firefox in windows. But I don't want to have another browser installed on my Linux machine only to access my router.

BTW, I don't like white backgrounds.

Half the time when I need to print websites to PDF, using print to pdf function, Firefox does not print the webpage properly. I know that I can probably go in the printing setting to change it for that page and that might fix the problem. But for my project, I need to do this nearly 150 websites everyday. So fiddling around with every other website and Firefox print setting is not an option. I have attached a sample print to PDF to show the problem. When I print, half the content is hidden. In contrast, whenever I use Google Chrome, I never have this issue. The default printing settings just work, every single time in Chrome. I don't want to switch to Chrome because I want to support the Mozilla/Firefox mission. But the minor issues in Firefox are frustrating.

Between the lack of a translation tool that can translate the webpage and the poor default printing setting, I am nearly ready to switch. Firefox developers, if you're reading this, please fix this printing issue. While you're at it, please add an inbuilt webpage translation tool. Nobody want to copy and past webpages to translate them. I really want to stick with Mozilla, but you have to improve these little features within the browser.

Actually never mind, cannot attach the pdf to show the issue in this forum. FANTASTIC (sarcasm)! Here is a sample screen shot instead. It shows what the print out looks like when "print to pdf" file is saved.

I have custom desktop app which can be opened from Web. IE, Edge shows just popup messages that such app is not installed. But FireFox reloads the page with the error (replacing my Web app) and shows The address wasn’t understood (yes, address doesn't exist but why doesn't it show just popup message without this error message)? Is it configurable,any suggestion to remove such reload? Thanks

On many websites FF does not show the saved username like it would show the password. I'm a web developer. How can I make Firefox show the saved username hint? I have seen this working correctly at the Twitter login, for example, but I don't spot any difference. Is Twitter using some JS to make that happen? There was an unsolved question a year ago about this https://support.mozilla.org/en-US/questions/1227914

As stated in the title, for some reason firefox likes to freeze itself, other programs and sometimes whole windows by using up 100% of disk. As windows resource monitor shows, this happens when mozilla tries to write a lot of stuff to profile files simultaneously, which happens every half an hour or so. The only addon I am currently running is adblock+. The amount of tabs open doesn't seem to affect when this happens or for how long. Usually open tabs are social media, yt, wiki and google docs.

I am on MacOS. I am using the most recent version of Firefox (75.0). When I go to upload a file in either Gmail or Google Drive, the filesystem dialog will not come up. The browser freezes for a few seconds, I get the beach ball, then it comes back with nothing have happened. I have refreshed Firefox completely, I have tried this in safe mode without any extensions, and none of it helps.

I tried a non-Google webmail solution as well and the same thing happens.
