Hi Mozzies When I try to play news videos from my local radio station I get this error. The videos originate from our local TV channel which uses Brightcove hosting. Safari and Google Chrome can play the videos. If I go to the source on the TV channel, I can play the video. Hardware MacBook Pro OSX 10.14.6. FireFox version 115.30.0esr (64-bit)

I am receiving messages from my banks that my browser is no longer supported or that I should update my browser but my settings mean Firefox automatically updates. However, I cannot read PDF statements even though I have Adobe Acrobat Reader installed and, on further investigation, I see that Firefox no longer supports Adobe Reader. I am a fierce supporter of Firefox but does this mean I have to use another browser?

After upgrading to WordPress 6.9 I can no longer see icons in the text editor, even within the theme I'm using. Also, when a box is checked (e.g. "Category" when you've created a post), the box is highlighted but there is no checkmark and you can't select multiple categories. Same for ANY box, actually. I've attached screenshots.

These issues do not appear when using Chrome. Really annoying because Firefox is my default browser and now I will have to do my WordPress development using Chrome. I really hope there's a fix for this, either via WordPress or Firefox.

Bank Accounts: I can no longer access my Bank accnts online. My Bank says they no longer support my current version (ESR) & I must upgrade in order to access accnts online. Don't know what to do.

I sent message below to Bluesky support and have tried all their suggestions (all relating to Firefox), but to no avail.

MacBook Pro OS 10.14.6. Yesterday (9Dec2025) I could open Bluesky & see my profile but could not add a new post. I then did an ‘age verification’ and received confirming emails. When pressing ‘New Post’ button just went to blank page. Under ‘notifications’ at the top, was a message “''''! r.countGraphemes is not a function''''”. I am accessing using ‘Firefox 115.31.0esr (64-bit)’. I have deleted caches, re-started ‘Firefox’ and re-signed into Bluesky, but problem persists.

Could you please advise how I can overcome this problem. Thank you, best regards.

I need to import my passwords from Bitwarden. I can export them from Bitwarden as a CSV file, but that doesn't show as an option in the Import Data window in Firefox. I use MacOS 10.14.6. Thank you, Tim

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!

Hi! I want to download the "Photoshow" add on. I can't because it says "Download the new Firefox and get the extension". When I check for updates it for Firefox it says I'm all updated. When I click the "download new firefox" I get the message "Your download was interrupted. But all is not lost." I really want this add-on. Is there another way to get it or to solve my problem? Thanks!

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.

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

I use multi-account containers extensively. Unfortunately, my laptop recently broke so I had to pull out my desktop which was in storage. I hadn't used my desktop in a few years, so I had to update Firefox to make it work.

Then I discovered that the multi-account container feature no longer works. It says it isn't supported in this latest version.

Is there any good way to fix this?

The multi-account container feature was what finally let me switch to the safety and privacy of Firefox. Prior to that, I used Chrome, but the multi-account containers were even better since I didn't have to tie a different account to each container.

It looks like I could roll Firefox back to an earlier version, but that would require creating an entirely new firefox account. It took me a substantial amount of time to get this one set up the way I like. I understand that you all want to protect my data, but frankly I feel like I've been put between a rock and a hard place.

Thank you for any help you are able to provide.

Firefox "Window" drop-down menu is missing open windows. This has happened for a few upgrades. If I add a new blank window, the drop-down menu will fully populate, though if I navigate to any of the other pages, it goes back to being incomplete.

I have installed the Firefox browser (latest version) on my MacbookPro and on a MacbookAir. How can I synchronize the bookmarks? Is this possible with iCloud? Thank you!!!

Hi, my shortcuts have all disappeared. I've looked on the browser.newtabpage.pinned and all of my saved websites are listed there. But when I open a new tab they're all blank and I can't seem to add any new shortcuts either. (Also I'm not good with technology so if you do have a suggestion on how I can fix this please tell me exactly where I need to type in a command or whatever because I didn't realise I could do that until just now.) All my bookmarks are still there and obviously it remembers my saved sites so? Thanks :•)

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

I've had a security breach where a Discord user got access to an email account. I'm going through all computers to make sure there is no malware that might be related to discord. I found one item in my download preferences that says "discord' but everything I've tried won't allow me to erase it. Any information on what this might be? and how/if I should erase it? (In fact, I don't know what any of the items are in my content types)

Hi, I would like to use my computer's built in print dialog instead of the one that pops up in FireFox. I know there is a button at the bottom of the dialog that allows me to choose my system print dialog, but when it comes up there is no way to view the number of pages like when I print from other apps.

I tried to use some online instructions using about:config, but it doesn't change anything. I would like to know how to turn off the FireFox dialog permanently. It only started happening in the last few FireFox updates.

I am running a 2010 Mac Pro in Mojavé and am using FireFox Version 115.11.0esr (64-bit). Please help. I need to see how many pages I'm about to print so I can decide which ones I want to actually print.

Thank you,

Jeff Hohner

I am using an older MacBook Pro running Mojave 10.14.6, for which the latest Firefox is 115.12.0ser (64-bit). It has always been working like a champ, but a few weeks ago, individual YouTube video pages look very odd. Usually the related recommended videos are along the right edge in one row, and below the default video window is the title, description, and then the comments.

The problem I have is that these two components became transposed, and if the video is displayed as full screen, the page can be pushed upwards to show the title etc got squashed below the video window, with the recommended videos still in a grid below it. I hope the included pictures are sufficient to illustrate the issue.

Another computer, an iMac running El Capitan 10.11.6, and Firefox 78.15.0ser owned by a family member, does not show this odd phenomenon. I must say I am quite intrigued by this, and would greatly appreciate any help my fellow members can offer.

I noticed an Other Bookmarks folder in my bar yesterday. Clicking on it showed 3 bookmarks: One labeled as move: https://www.lyricsondemand.com/tvthemes/rawhidelyrics.html One for Google And one for my bank account with log in information all filled in so that you only had to click submit to get into my bank account

I didn't create any of these. What is most disturbing is my bookmark for my bank account log in is first enter username, hit submit, then password is auto-filled in the next screen, hit submit to log in and see account details.

Again, I didn't create any of these!!! How can I see when they were created?

Can I see how they were created?

Anything else?

This is of course very disturbing!

I have changed my log in and password and checked off every notification feature in my online banking privacy area.

Thank you

Shaun
