Various website that contain dynamic content are not being rendered by Firefox to display that content. This is happening with websites that provide transportation information and ticketing, including Amtrak and Peter Pan Bus Lines . It is also happening with a genealogical website, FamilyTreeDNA, on pages that should be displaying family tree information. Illustrations of two pages are attached. I have been able to access the information by using Opera on this same computer and operating system, and by using the same version of Firefox installed on a different computer with different operating system. I am not sufficiently proficient with website development to know or understand what type of dynamic content is being generated by these websites, or how Firefox interprets the content. My suspicion is that some Firefox setting has been enabled or disabled, but I do not know which one it would be.

Greetings, I've checked a few articles in Firefox to help with my question, but none of them are helping. (Here's the main article: http://example.com.) Here's the situation. Say I go to a website's Contact page and click the button to contact someone, a window appears and asks me what app I want to use to open the email. Gmail is my default email, and Firefox is my default browser, and I use Windows 10. When I open the window of options (see attached screenshot) to open the email, and I then click "Choose Other Application" (other than Firefox), I don't see the Gmail app anywhere. I then followed the directions in that link above to check my Windows settings, per its suggestion, which I did ... but in those settings, too, I got to a point where the directions no longer matched what I'm seeing on my screen. I didn't see the Gmail app anywhere. Could you let me know in simple layperson's terms how to open Gmail links in Firefox? I don't have a PhD in computer science, so please keep it very simple. Thanks in advance! Best wishes, Bill

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

I am using Ancestry.com - and Firefox keeps trying to autofill fields it has no business with or understanding of. While autofill is handy at times, it's a downright nuisance - making my research way more tedious because I have to continually erase its autofilled data as erroneous. Is there a simple and temporary way to stop autofill?

Hi, Just installed Ubuntu on a new laptop, with Firefox. No add ons.

Have changed my homepage to www.duckduckgo. Have changed my default search engine to duckduckgo. In about:config my browser.startup.homepage says www.duckduckgo.

Have also changed browser.startup.homepage_override.buildID to www.duckduckgo.com and browser.startup.homepage_override.mstone to www.duckduckgo.com

But STILL, every time I start Firefox, I'm taken to google.com. Please cn someone tell me how to stop google coming up when I start Firefox.

Thanks, Ivan

i had a big problem with windows 10 action center (it won't open at all) only one solution was creating new Microsoft profile and move all files from one to another (including downloads documents desktop and whole appdata folder with firefox inside included)

and theoretically all works fine. I have my firefox account, history, tabs, favorites, theme and plugins, but they have blank icons and doesn't work.

is there any way to automatically redownload and reinstall plugins?

I would like to add that I have 3 browsers (profiles) and different plugins in each.

Is it possible to remove favicons from the Bookmark Tool bar and bookmark pulldown menus? It'd be a much cleaner look. Not entirely sure, but it looks like someone was asking a similar question here: https://support.mozilla.org/en-US/questions/1258765 If by any chance pasting his contact here reaches @jscher2000 perhaps he has some input. https://support.mozilla.org/en-US/user/jscher2000 Thanks!

How can I do keyboard shortcut, "Text encoding options", then "Unicode". I have it on toolbars. Like on screnshot, I pint mouse, then I need to select Unicode, which is bothering. I am opening many many pages, which are always different than unicode.

Firefox used to allow a hack to add a custom search engine to the search engine list. This allowed users to make custom engines the DEFAULT search engine. (Engines can be added to Bookmarks but then they require a keyword to activate. Default engines do not require a keyword to activate).

The way to do it was: 1) place a folder called "searchplugins" with your custom .xml file describing your search engine (i.e.,, a URL with a %s added to it) inside your Home folder on a Linux OS.

2) open the Web Console

3) input: Services.search.addEngine("file:///home/user/searchplugins/custom-engine.xml", null, null, false);

4) now your custom search engine would appear in the search engine listing in Firefox and could be made default

On recent Firefoxes, this no longer works. When I inter the Sevices.search.addEngine part to the Web Console, I get this message: "ReferenceError: Services is not define"

I've been using Google Chrome because of stuff like this. Firefox just doesn't allow me to do what I want to do. But I appreciate Mozilla ideals and am trying to give Firefox another chance. But it is contingent on being able to make my custom search engine the default search engine.

Is there a fix for this error I'm encountering in the Web Console?

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

I want to setup firefox to ask me, or directly to switch to a webmailaccount and start an email, if I use a MAILTO link. I can not setup this, the only add-ons are for gmail or yahoomail , but I can not find a solution for a custom webmail address. On another PC I got a question from firefox if I want to define this link, an on this PC Mailto is working. On my working PC I also want to set up this function, but I can not manage to do it. can anybody help?

The option to always open a link in a particular container seems to be linked to the domain; right-click link, Open link in new Container Tab, click the Always open link in this container. This then sets all links to that domain to open in that container.

Often I want to log in to the same domain, but as a different user. So I open them in different containers so as to keep the sessions separate.

It would be useful to specify the container in the bookmark rather, so I can have multiple bookmarks all pointing to the same domain, but each always open in the container I choose for them. I tried various add-ons, but they use the domain-based container feature built into FireFox.

How can I force a bookmark to always open in a set container?

My computer shut down after I tried to update Malware Bytes. After the restart, my Firefox home page doesn't pull/show the Top Sites or Highlights (won't even let me manually add). I ran a scan and computer s clean, no viruses and version is up to date. I even tried a refresh of Firefox, but same issue.

I love Firefox screenshots. However, On copying a screenshot, I receive a notification. I want to disable these notifications. I tried disabling web notifications but that did not help. Is there any way of doing so? Thanks!

Firefox 75.0 has just been released. Address bar has been ruined with dynamic size and lines with increased height. For some unknown reason Mozilla developers think that taking away more vertical space will help their browser have "Focused, clean search experience that's optimized for smaller laptop screens" as they state in the release notes. Outrageous.

Now tell me how to go back to the old behavior.

I want a full horizontal length search result widget as it was before.

I DO NOT want an ENLARGED address bar while searching. Simply annoying that it changes its size and looks like popping out from the upper top toolbar every damn time I type something into it.

I want the ORIGINAL LINE HEIGHT of search results in the expanded address bar.

I want an address bar that doesn't expand when focused with Alt+D, like the old one.

I haven't found an about:config option to restore old behavior. However, a userChrome.css workaround is still good for me.

Is there a preference to disable the expansion of the urlbar (aka address bar, awesome bar, mega bar) without disabling its new features? When expanded, it covers part of my bookmarks bar and makes it harder to click the bookmarks. Also I dislike the chunky UI look.

Things I've tried that did not solve my problem:

• browser.urlbar.megabar: This is gone in 75.0.
• browser.urlbar.update1: This disables the expansion, but also disables the new icons, suggestions, etc.
• browser.urlbar.openViewOnFocus: I don't know what this does but it wasn't it.
• ui.prefersReducedMotion: This disables the animation, but the bar is still expanded.
• Search with the Firefox address bar: There is no information there about the expansion.

I'm hoping there is a browser.urlbar.update1.expand or similar that I can toggle off. If there definitely isn't, please confirm so I can submit a bug.
