I need to access Canvas as part of my school coursework. As of yesterday, Canvas refuses to load in Firefox. I've restarted my Mac, made sure Firefox is up to date, and tried running Canvas in Chrome, where it worked just fine. My internet connection is also stable. All other websites seem to be working in Firefox, but for some reason Canvas doesn't load after any amount of time and the interface appears as the attached image. Any help? Firefox is my preferred browser and I actually cannot do any online coursework without Canvas, so any suggestions or advice are very welcome.

Have not been able to log on to a few sites (all financial base: bank etc) since approx April 2023 Have done all the dirty dozen: cache/update FF/reset/ disabled ad blocks etc.) and still no luck: had to revert back (after about 10 years) to safari (ugh) scoured back in archives for similar problems but found no answer. Does anyone have any idea? (i have not upgraded my mac os 10.14.06 and require itunes to remain) Thanks

I just installed Firefox on my iPhone and can't seem to sufficiently customize the homescreen. Specifically I can't find a way to delete 'Amazon sponsored' and 'Expedia sponsored' from the buttons that appear. I don't have use for these or any other corporate sponsored buttons and don't want to see them. My goal is to take better advantage of syncing to Firefox for Mac, and these buttons seriously interfere. It's also not letting me change the order of the buttons to better match my laptop screen. Please advise.

I've had this for a few months now and it's driving me crazy.

I have blocked reddit.com, http://www.reddit.com, https://www.reddit.com, I delete the cookies, it keeps coming back. So I finally deleted every trace of Firefox off my computer, deleting the library files, everything. I download a brand new copy of Firefox, start it up and within seconds have a reddit.com cookie. There are no reddit pages open, no tabs, no nothing.

Also, I keep reading that you can right-click or control-click on a cookie to inspect it but that does not work for me on FF 115.4. I cannot find any way to look at the cookie code in Firefox.

I'm on the verge of just giving up on Firefox at this point. Any help would be greatly appreciated.

I'm downloading a lot of images, and every time I do so a popup box appears showing the most recent five downloads and a button to show all downloads, It covers some of the icons I use for downloading images which is frustrating. If I right click on any of the downloads one of the options is to Clear Preview Panel, so I assumed it was called Preview Panel, but help does not know about that and I can't find how to stop it coming up (it used not to until I did something, I don't know what) It's driving me crazy.

Starting today, amazon web pages are not updating correctly. The amazon web page appears normal till I sign in, then it doesn't update "cart" contents or show account holders name or list any "Lists" when accessing account saved lists. I have deleted entire history, and all cookies and caches X 3. I Rebooted computer along with a "system command control reset" and still the pages are not loading correctly. Short of reinstalling "Firefox" what more can I do? Are there any "Preference" files or files with specific extensions I can delete? Thank you. Gerard

For years I have used Firefox and every update has been seemless. This one is terrible!!

Every time I click to open a new tab, it opens a new page Every time I try to change tabs from previous to the update, it will not change. I am stuck on that tab Every time a new page is created I cannot open it because it has a "block pop up windows" and this is a setting that I did not change. I have had to turn off all blocking just to be able to change my password, to be able to typoe here.

You have basically stopped my studies until this can be rectified and I doubt anyone will repond to this message

Asked earlier about deleting and doing a reinstall. Would that mean losing bookmarks, profile etc.? I have backed those up and would like to know if anything else might be required.

YoutubeTV is suddenly not working on Firefox, fine elsewhere ... they suggest doing complete reinstall.

I would like to be able to control which OS and version is reported by my browser to sites like https://www.whatsmybrowser.org/ . I can do about:config but I don't see which setting has that info, to change it. I also see a User Agent Switcher extension, but it doesn't let you set the version of the OS. https://www.whatsmybrowser.org/ clearly shows my OS and version, so I know it's there somewhere. How do I change it?

I noticed recently that the "+" for new tab is no longer displayed and available. I have to go to File/New tab to open a new tab.

Does this happen only for me or it is a change that was made? What should I do to have it back as it used to be and it is displayed here:

Thanks.

I have a neuro issue where these trigger my migraines.

And they've become standard web design.

I currently reduce layout.frame_rate to 1, which *helps* unsmooth scrolling animation. That's often enough to navigate pages with narrow sidebars, or with good visual contrast between the sidebar and the content. But it's not enough on pages with extra-wide sadobars and no visual contrast, such as Wikipedia's "Vector" redesign, or the Internet Archive's latest redesign:

https://en.wikipedia.org

https://archive.org/details/texts?tab=collection

I can force Wikipedia into mobile, which helps, but I'm not aware of a similar fix for the Internet Archive, and really need a global fix.

I can get reasonable behavior from the Internet Archive if I reduce the window to about 640 pixels, ... but instead of a non-scrolling sidebar taking 1/3 of the screen, I end up with a non-scrolling desktop taking up 2/3 of the screen!

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

I would be so grateful if anyone has a solution!

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I have a good 1080p monitor, which I can set up in either orientation. I have a hard time finding monitors which meet my accessibility needs, so a square/squarer monitor or a 2nd monitor would be expensive.

I have tried setting it up in vertical mode, to make it easier to read pdfs and to write. And ideally, to make it easier to avoid sidebars and/or move them away above the main content where they're less likely to trigger as many @##$% migraines.

I've noticed that most websites are designed for the horizontal layout. Elements disappear off the right edge, sometims with a horizontal scrollbar to reach them, sometimes without. Is there a trick to get miost or all websites to fit?

I use about:config fixes, add-ons, and user css to try to increase font sizes, switch colors, block animation, and reduce frame rates to completely block "smooth" animation. I can't do without these, so I don't think I could adapt the mobile version to my needs.

I've noticed *many* other problems in other apps, but if I can get all these websites working in Firefox, I can probably sort out the other problems elsewhere.

A few days ago, Firefox updated itself. Suddenly, every link opens a new tab that says "Anti-phishing Protection is scanning your link..." and the original tab opens a window that says "Anti-phishing Protection - You are attempting to open an insecure link. Are you sure you want to proceed?"

I cannot find anywhere to turn this off or fix this ridiculous situation?

For the last two days, cnn.com won't load and gives a message that the browser is blocked. Can you explain how I can remedy that? It's a rather popular site, so I assume Firefox will want it to work. All my other sites are working fine, so I'm assuming it some adjustment that cnn made on their end.
