Firefox Support Forum

Why isn't the Restore Previous Session choice available on the Open Application Menu? Even if I click the checkbox under Tools/Settings/General/Startup: Open Previous Windows and Tabs (version 107/windows 11), I am presented with a tabula rasa screen on reopening my Firefox session. Your help/support says to go to the Open Application Menu/History and choose Restore Previous Session (located between Recently Closed Windows and Clear Recent History). However the Restore Previous Session is not listed. Not sure why Firefox can't get this right since you have had it right for the almost 20 years I have chosen it as my default browser.

No Video with Supported format and MIME type found is not allowing me to play videos on website.

No idea what's the cause of it, I've tried everything from internet tips how to solve this.

With the latest upgrade to Firefox 107.0 there is no option any more to import or manage certificates. Going to Settings/Privacy & Security/Certificates and selecting View Certificates results in a window showing installed certificates with only OK button at the bottom of the window. No option to import, delete, save or anything else. OS: OpenSuse Linux 64bit

Firefox not loading and missing VCRUNTIME140_1.dll preventing re-installation. Full message is: 'The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem.' Tried to install an old version of Firefox (28.0) but this is not upgradeable.

More and more websites are alerting me that they are not fully compatible with Firefox and that I should instead use Chrome, Safari or Microsoft Edge. Recent examples are Allstate Insurance and Hewlett-Packard, not exactly insignificant players in the business world.

Here's what Allstate had across their page when I was attempting to log in:

"You may not be able to use certain My Account features on your current browser. For the best experience, consider using the latest versions of Chrome, Safari or Microsoft Edge."

There have been other websites with similar messaging about Firefox. The issue seems to be growing. Is there a fix coming from Firefox or are we going to continue to lose compatibility?

Hi, I need to install a digital certificate. The instructions I have are... Tools>options>advanced>encryption>view certificates>import but I can't find anything past "tools" Thanks, Katrina

Normally I use side-berry to hold all of my tabs - the panel normally collapses and hides to the left of the screen - showing just the favicons of the website.

After the most recent firefox update 107.0 (20221110173214) there is now a large bar that i can't remove!

I have a CSS file for appearance, which i have included below.

any idea how to shrink this dead zone? I would really like to keep using my fun tabs.

I use the userChrome.css file to take the search bar from the bottom of the screen and have it float. Here's the instruction that I use ... .browserContainer > findbar {-moz-box-ordinal-group: 0; position: fixed !important; }. Firefox 107 has made that .css instruction non-executable. If I text out the instruction I now get the search box at the bottom of the screen. I want it back to a floating search box. Is there a fix in 107 so I can use my .css file or is there another way to get the search box floating. Regards

I have reinstalled Windows 10 in a new computer, installed a fresh copy of Firefox, and successfully imported my bookmarks from the original computer. But I cannot discover how to export and import my bookmarks toolbar. Another user has attempted to answer the question, but the description is very ambiguous and I can't understand it: https://support.mozilla.org/en-US/questions/1266729. The following "official" page also does not deal with the issue: http://kb.mozillazine.org/Sorting_and_rearranging_bookmarks_-_Firefox. I would have expected that there would be an "Import or Export Bookmarks Toolbar" facility somewhere, maybe under Menu | Bookmarks | Bookmarks Toolbar - but no luck. Could an explanation be provided?

I logged into my website using Firefox, 3 days ago and blamed the server for not allowing the images to appear in the Media Library properly. It took several attempts before the images would appear properly.

Today, when trying to upload a tiny 43KB image, the same issue happened, and again I blamed the hosting server.

However, I have tried uploading the same image to 5 different websites, using Firefox and the SAME thing happens. This time, it doesn't matter how many times I upload and delete the same image. It simply refuses to be displayed.

Back to the site I want the image uploaded in, and I used the Opera browser... POOF! Image uploads FINE and displays PERFECTLY in Opera, as well as AFTER logging out. Checking with the Brave browser, yes, it too sees the image... but when I try viewing the page in Firefox, the browser REFUSES to load the image.

I've tried 2 different computers using 2 different IP addresses, and an Android device, using Firefox and NOPE, the image REFUSES to load.

What is going on... am I the ONLY one experiencing this issue?

I've cleared cookies, I've rebooted my working computer... I've exhausted EVERY attempt at my end in trying to figure this out.

Can ANYONE shed some light on this issue please? I have many visitors to all of my sites that use Firefox, so this HAS to be resolved a.s.a.p.

Thank you in advance, Trish

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

how is it that the usps website works on edge, but not on firefox? usps stopped working about a month ago on firefox. i already tried clearing the cashe and cookies from usps and that did not work, and neither did turning off ad block plus. im at a loss here.

Please allow me to preface with I do not know how to code at all and I have found some options to make the scroll bar disappear, but with coding, and I'm hoping for an option that takes that away easily.

I don't think it is any of my extensions causing this, and I don't think it's an option in Firefox to remove the scroll bar.

Please help if possible! It doesn't disappear even when I'm watching videos on fullscreen.

Thank you.

My problem is a new issue with Firefox and CenturyLink. I tried chatting with Century Link and they keep referring me to Firefox so here is the issue. In October I was able to log in to Century Link and view/download my current bill. This month when I try to view the bill all I get is a grey screen and no data. I have been forced to use Microsoft Edge which DOES allow me to view/download the bill. Also, the Chat feature on Century Link via Firefox does not work. It does work in Microsoft Edge. Something in Firefox changed in the past month and I haven't a clue what it is.

I have hit "save" when the "do you want to save password" pop up appears many times, but for some reason when I check my logins in about:logins, there is nothing. I tried to manually save a login information with Create New Login, but it tells me "An error occurred while trying to save this password".

I must've accidentally pressed a button last night while I was watching a YouTube video on my desktop, as now the right and bottom edges are cut off when the video is in standard mode. Refreshing hasn't fixed the issue, neither has restarting or shutting down my laptop, as it was turned off for 12+ hours and I still had the issue when using YouTube today. It's even an issue in incognito mode, but not an issue if I use a completely different browser. I can't find anything else that has been affected by whatever button I must have pushed. Laptop is a Dell G15, if that's relevant. Would love any tips to fix this.

Hi,

I have today logged in to a specific webpage on my energy providers website and find that Firefox does NOT display the option to open a chat which is clearly displayed in the Chrome Browser (Screenshots attached).

I have navigated to "Settings/Privacy & Security", scrolled down to "Permissions" and can confirm that the "Block pop-up windows" option is NOT enabled.

I am obviously missing a setting somewhere, can anyone advise?

Thanks

'Read aloud' function: how to organize it for my html files?

In Firefox I see and can use the button 'On|Off read mode F9' on this page, where I write the question.

But when I open my page, this button is absent and F9 doesn't work. (for example, this one: http://accelerometers.000webhostapp.com/ ) Also I want to get 'Read aloud' possibility for txt files (I edited them and save as html files) What should be done to provide this possibility?

Note: in MS Edge my html files are read aloud.

Best regards, Vadim
