Before update when I clicked in PDF viewer toolbar download button it opened a screen to open with, right now it only download a file. I want it back. I have firefox as pdf viewer, but sometimes I need to open file with Acrobat DC, that's when I did click download button. It works on other computer like before, it is before firefox update.

I've noticed for some time now that when I access the history tab and see what there, there is nothing in it. In the past when I accessed it, it would show the sites I had visited. Not any longer. How do I fix the problem?

This is more of a convenience issue but the new download panel pop-up from the download arrow is very distracting. I couldn't find an option to turn it off so I had to go into the config and turn the true flag false for this "improvement". Is there a better way of disabling this pop-up and if not will there be in future versions of firefox?

Hey, I can't add new filetypes to the handlers.json Who had this before? I have already reset Firefox, deleted handlers.json, used safe mode... all without success For example, when I click on a ZIP file, the "save as" menu opens immediately. In the FF settings this filetype does not appear. So I can't define how to handle new files. I have also tried the addon "Content-Type Fixer Content-Type Fixer".

I have set the Noto family of fonts to be the default font family but websites that don't specify a font or specify sans-serif or monospace get Liberation Mono. When I changed any option in the fonts settings, the entire browser becomes Liberation Mono. I want Noto Sans be the default font for websites and for the Firefox UI. I tried to fix it by preforming a Firefox Refresh, but it didn't work. I think the problem began after upgrading to Firefox 100 but I'm no 100% sure.

Hello,

Firefox just updated to v100.

However, my menus (e.g., bookmarks, tools, history etc) and popups text has become black, having previously been white. The Menu Bar and Tabs text are still white.

How do I get the White text back on menus and popups please?

Thanks in advance.

It seems since Firefox 100 the address bar has taken to being white-on-white, making it nearly impossible to read. There isn't any issues with light themes. It doesn't matter if I change the Windows 10 default app mode to light or dark. Light themes have black text on white background, but dark themes have white text on white background. Any ideas?

Hi,

I would like to change the light grey hover color on menus (e.g. yellow), see attachments, probably using userchrome.css.

Does anyone know the correct code to do this please?

Thanks in advance.

If i want to open files into an application i do not want the files to clutter up my downloads folder.

this used to work perfectly pre-v91.

i understand that some users were confused where their files went when they opened them incorrectly within firefox.

currently i'm using a python script to clear my downloads folder from the useless files, but i'd rather just not have to bother with it.

is there a way to get the old behavior back? im comfortable going into about:config and/or using a plugin if i have to.

The Firefox desktop browser default font is replacing all fonts on some websites, only title fonts on some others, and then leaving others unchanged. It seems random, and I can't stop the default font from taking over randomly on most websites no matter what I do. This was not happening until today, and no browsers or general MacBook Air preferences were changed between today and yesterday when I last used the browser on desktop.

Under Firefox Preferences » Fonts » Advanced, I've made sure to check the box to "Allow pages to choose their own fonts instead of your selections above", and I've unchecked it, and I've re-checked it, and the default is still overriding fonts on most websites.

I've quit and restarted Firefox 3 times.

Help!

how can I restore to white, the black background on the Firefox Browser, even my menus have turned black. I have tried through my normal settings and although it states I have a white background. It doesn't

Is it possible to move the address bar above or below the Bookmarks Toolbar in Firefox 100.0 (64 bit). If not, can you provide a link to the latest version of Firefox for Mac OS X Catalina (10.15.7) that does not have the address bar on the same level as the Bookmarks Toolbar.

Many thanks.

On the page: https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu#w_downloads-panel-automatically-opens it says: "Downloads panel automatically opens" "Every time you start a download, Firefox will automatically bring up the Downloads panel by default, . . . "

It never used to do that ! Having the Downloads panel drop down and just sit there covering a large part of the page every time I save a little picture is an extreme nuisance ! How do I prevent it from happening ? Please help ! Many thanks !

I always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced

Hi,

Since upgrading to FF100, almost all of the 'select' boxes on my webpages have white text on a white (or very light) background, and are only visible when hovered over, see attached screenshot.

How can I rectify this please?

So, for a few months now, the preview panel in Firefox has been popping up with every successful download of a file from online. Its a bit inconvenient because anytime it pops up, it basically tabs me off a page and interrupts my writing or the like. This wasn't an issue last year when after successful downloads, the downloads icon in the toolbar just lights up blue to signify a successful download. The preview panel popping up every time Firefox successfully downloads something (due to reasons, I download files in bulk from multiple sources) is incredibly irritating. The problem goes away when I just remove the download icon/panel from the toolbar entirely. I just wanna know WHY this bizarre phenomenon happens.

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

I am in the USA. Every time, on any page or website that I need to provide credit card info, when I click in the box to type in the CC numbers/expiration date/CCV, a window pops up as it should (for auto-fill) with my credit card information. In that window, I can scroll over the different credit cards, click on the one I want to use, and it SHOULD auto-fill into the box where the numbers would normally be typed in. Now, the window still pops up and I can scroll over the credit cards and choose one, but when I click on any of the particular credit cards, the auto-fill doesn't work. The boxes in "settings" are checked to allow auto-fill. It worked for months, then just stopped. Thanks for your assistance!

Recently, most of my PDF files that I open with Firefox have changed their icons from the Firefox HTML document icon (the purple icon in the image attached) to the Firefox PDF icon (the red icon in the image attached). Is it possible for me to change the icons back without downloading third-party software?
