I use html pages on an internal hard drive that link to pdf documents. For some reason since Version 91.0.2 was installed I can not get the pdf documents to open with Adobe Acrobat Reader DC.The new version insist on opening the pdf's in the Firefox web browser. When I click on a pdf link at an external website the files will open in Adobe Acrobat. I used the code below to test the open in Adobe Acrobat execution and it works on the w3School example. When I run it strait from my hard drive the document opens in the Firefox web browser. 

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <h1>PDF Example</h1>
    <p>Open a PDF file <a href="datasheet_cube-model-715.pdf">example</a>.</p>
  </body>
</html>

Please let me know if there is a solution. Thank you,

I've been using Firefox ESR for some years. Now I would like to know the best way to use and try the "normal" version of Firefox. Can I install it without uninstall ESR? Or must I do a clean install of Firefox after getting rid of ESR? If this is the case, what must I do to keep my profile, bookmarks, etc?

Unable to disable search from address bar

Since Firefox was last updated, I now no longer have the ability to access some websites such as Google, Wikipedia, and Amazon without Firefox prompting me to type something to search within those sites even though all I want to do is go to the home page.

I can still get there by typing http:// in front of it but I shouldn't have to and if I change the settings to add the search in the toolbar and then try going to "amazon.com", for example, I'm still being prompted to use the address bar to search.

Is there a way to fully disable this prompt so I can type in "google.com" or "amazon.com" without getting the search prompt?

Recently the majority of content types have disappeared from the Applications section in the Settings. (See the attached screenshot) Even Word and other MS Office files are not on the list any more. Consequently, when I open a Word file, Firefox asks me where to save it and does not offer to either save it or open it.

I tried editing handlers.json file and added an entry for PDF files. Now upon clicking on a link that leads to a PDF file, Firefox prompts me to open it or save it. However, if I choose to open it, the file gets saved in the Downloads folder, rather than Temp folder like previously. The result is that the Downloads folder gets filled with files that I have opened but did not want to save and keep.

I created a new Firefox profile to see whether the previous list of content types would return. This did not work, and the new profile, too, shows only a few content types.

What could be the problem? Thanks.

Firefox not showing the "X" in Settings checkboxes!

Systems: MacMini (2018) running Mojave 10.14.6 Windows 10 Pro v20H2, build 19042.1165, experience pack 120.2212.3530.0

Ever since FF v89 when I go into FF Settings in either system none of the options I have selected display an 'X' in that option's checkbox. In previous versions when I clicked in an option's checkbox an 'X' would appear and disappear when clicked again.

No more.

I've tried changing the theme to Dark, Light, System . . . no change to this issue in either my Mac or pc: I cannot see an 'X' in any option's checkbox in FF Settings.

Please see attached screenshots. They are with "Dark" theme, but its the same no matter what theme I choose.

How to get my Settings choices to show that I have checked off this or that option?

Solution??

Thanks!

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

Does Mozilla have such a service for Firefox sync?

There are multiple screenshots attached below, 2 of them showing setting marked in red. Those settings are pre-configured with the firefox.cfg file. I would like to also pre-configure a list of other settings. You can also find those other settings below.

Anyways, i remember someone from this forum told me there is no "official documentation" for the firefox settings which are listed in about:config. Is there an "inofficial documentation"? If you could reply with the exact setting that i have to change according to the screenshot attached below that would be awesome, otherwise an URL for some sort of documentation would be welcome..

Basically all the setting i want to change exists and can be manually edited using the firefox settings, but theoretically could be easily pre-configured with the firefox.cfg.

All i need are setting-names/ids.

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

An address is a URL. A search is keywords. They are not interchangeable. How do I get Firefox to stop mixing them up?

When I want a URL, I type it in the address bar. Search has no relevance to a URL, and any intervention of Search gets in the way, and creates errors.

When I click in the search bar, it's because I want a keyword search with one of the search engines. A search is not a URL.

They are two completely different things, and treating either one as the other is error. I do not want Firefox to kidnap my cursor and teleport it to somewhere I didn't click. They are two entirely different spaces, they are not interchangeable. When I click in the search bar, it's because I want a search. Don't you dare second guess me and change my click to the address bar.

How do I turn off this stupid stupid stupid error behavior of FIrefox?

I tried this and it didn't work. In about:config • keyword.enabled and toggle it from True to False. • browser.fixup.alternate.enabled and toggle it from True to False.

Under: about:config browser.taskbar.lists.recent.enabled false

I have just made a Windows 10 system and I am not understanding the features now existing that weren't with Firefox on my Win7. I have turned the 'Frequent' off and now right clicking the Firefox icon produces 10 'Recent' listings. Being that I've changed FF's config to false, I do not know how to make these 10 'recent's permanently disappear. Right clicking one of these entities and removing only replaces with another.

Please help me to permanently remove 'Recent' from my right click of the Firefox icon in my taskbar.

I have an account on usps.com (the post office). Using FireFox, I am unable to see or use my address book on that site. USPS tech support says it's there and also says FireFox is the most problematic web browser of all. USPS tech support says to use ANYTHING but Firefox.

Yes, I have cleared my cache and cookies multiple times in an effort to solve the problem. And doing so does not solve the problem.

I can use IE or Chrome to access USPS.com and I can see my address book!

What the heck, Mozilla?
