    I'm currently in my vacation home and I don't have home internet here. I'm connecting through my mobile phone using limited mobile data. and I selected not to download updates because it keeps updating itself like twice in a week and every MB counts in limited data plans especially if it's just 4 GB total for each month.

    But now every time I open the firefox it showing download latest update popup like an annoying virus on the top right corner where 3 horizontal lines are located.

    I checked the internet and previously this was an option in it's settings. Then this option removed and only hidden behind the about:config . and now it's completely removed from about:config either.

    The only reason I switched from chrome to firefox was because google became an absolute dictator lately and all it's changes was to limit down my accessibility. I switched to firefox becuse it doesn't backstab it's users and they give the choice to it's users rather than dictating it like dictators. So did I make a mistake switching to firefox? Is firefox becoming just like chrome now? or is there (hoping so much) and option given us to turn off the notifications as well?

    Spontaneously, Firefox is now unable to load certain websites properly: Twitter won't show tweets, streaming websites won't play, and sites like Wikipedia have lost their formatting. Other websites seem completely unaffected, like YouTube, Pinterest, and news sites. This is only happening on Firefox, as my other browsers are unaffected, but Firefox is my default and I don't want to have to switch.

    I've tried restarting both the browser and my PC, clearing the cache, turning off my firewall and anti-virus, disabled add-ons, and unregistered service worker... I'm out of ideas.

    I've included some images to show what I mean.

    My situation is probably unique but basically, I have a new computer. On my old computer I had a fair few windows open. Because of a lot of different issues (bad battery, no working charger etc.), I have access to the hard drive of my old computer but I can't turn it on anymore and it died before I could reopen most of the windows on my new computer. I'm able to use the hard drive as an external hard drive to transfer everything to the new computer as needed So, I know it's possible to get back bookmarks by transferring the files. I also know that there is a recovery file somewhere in the firefox folder which is used when hitting "Restore previous session" to get back the previous windows Would that mean it's possible to find the file from the old computer's hard drive and move it to the same folder on the new computer to use for the restore function in a similar was as the bookmarks?

    I updated Firefox yesterday and since then everything in Firefox is blurry, except for some drop down menu's for some reason. Everything else is... I use two 4k 60hz monitors. On both of these they are blurry. It also seems like everything moves up and down a pixel when giving input (like keyboard or mouse inputs). I added an image of the blurriness. Does anyone know how to fix this?

    Note: This is the only software experiencing this problem.

    Best regards

    When hit shift and click somewhere in the webpage or type something, the "Page Inpector" keep poping out (see attached screenshot), this is so annoying that I basically cannot type any capital letters. I have tried the option "Refresh Firefox", the browser seems to be set to default mode, but the issue still exsist. Tried for a new keyboard, the same. I searched the forum, but unfortunately cannot find a proper solution. Hope anyone can help me with this, otherwise I have to consider to change my default browser (which I really don't want to because of such a simple but annoying problem).

    Thanks a lot for anyone could provide any suggestions !

    I saw this answer https://support.mozilla.org/en-US/questions/1303747 but I don't understand anything from it, English is not my first language. Will I lose my bookmarks and extensions? Do I delete the folders in program files or run the uninstaller? When running the installer there is an option to "restore default settings, remove extensions etc", should it be on or off?

    I deleted the folder, ran the installer again and set the option to restore default settings off, and still can't open firefox. Can someone explain in simple terms?

    I've already found the solution, but wanted to share that Version 90 created a problem with Print Preview and Shrink to Fit. Uninstalling Version 90 and re-installing Version 89 fixed the problem. With Version 90 the Print Preview function (which I love) didn't work properly. When I try to Shrink to Fit any page, the first page shrinks, but the second page isn't pulled into the first page. Also, there's missing information on both pages. If there's another solution so I can use Version 90, please tell me. If not, and Mozilla is doing away with Print Preview (and Shrink to Fit), I'll have to do away with Mozilla Firefox. Sorry, but that's the main reason I use Firefox over Chrome. Perhaps I can find another browser to do what I want. I hope not though.

    First of all excuse my English because it's not perfect. The problem came with the new version 90.0.1. There are some websites I visit every day, and after installing new version of FF I noticed that the fonts used in websites are different than it was before. Some websites are breaking apart and doesn't look like they did before, and like they look in other major browsers right now.

    Examples: http://www.alterego.co.rs/_knjigovodstvo/aktuelno.html https://www.arrowheadpride.com/

    I went to the Settings option and saw that my FF is set to show Times New Roman 16 as default font, but if I go to Advanced I can see that the checkbox on Allow pages to choose their own fonts, instead of your selections above option is ON. So websites should be shown not by default font, but the font used in websites. But if I turn that option OFF, than I can see websites like it should be, like it was before new version, and like it's shown in other major browsers. But it gives me wrong look (font) with some other websites, so it's not the permanent solution. I guess it's some kind of problem with new version of FF.

    Note: Same thing happend a couple of weeks or months ago with one of previous FF versions, but that was fixed just day or two later with another new version. It looks like we have simmilar problem right now.

    Thanx in advance for any help, and I hope somebody will fix that soon. I am lifelong user of FF browser because it's my favourite and the best, but that kind of problem can be pretty big for someone who is very often online and who is working in developing websites sometimes.

    Thanx again Dragan

    1. When I have to move another windows across FF, I get a string of repeating images one of the other that I cannot remove until I close that FF page. (See image below)

    2. When I save a FF page, it does not close itself. I have to click on the page, refresh it, then I can close it. Also sometimes it take 20-30 seconds to save and close a page that has mostly text on it, such as an article page from one of the many newspapers I review every day including Financial Times, NYTimes, Wash. Post, etc. Due to this and other errors, it slows down my work day to where I am forced to spend one to two extra hours workiing to correct these errors.

    3. When I have FF open, it seems to slow down my entire machine, even though I'm not working at the moment in FF.  
    

    4. Please fix this. I work 7-8 hours a day on a project I am nearing 20 years completing. It gets tiresome in and of itself, but when FF causes me more problems it become exasperating and as much as I want to quit, I can't walk away from this project which has grown to nearly 700 gigabytes in size with millions of pages of html, jpg, pdf and txt files.

    5. Please help me with a new update that will fix these errors or tell me how I can fix them.

    Thank you.

    Is it possible to lock Firefox extensions? By locking i mean make the extension inaccessible (prevent disabling it or changing it's settings but having it still work).

    https://github.com/mozilla/policy-templates/blob/master/README.md#extensions

    Does this "lock" mean what i just described?

         "Locked":  ["jid1-p8wT8wUxc4KaJo@jetpack"]
       }

    }

    That is in my policies.json file, is this how it's supposed to work since it does nothing for me? I'm not sure if the id is correct, could someone tell me how to find the right one and if this is right, then what's wrong? Thanks in advance.
