Firefox is my longstanding browser (on Windows 10). I wish to make use of the Firefox PDF viewer, but have been unable to gain access to it. If for the purposes of an attachment I click on "Open with", Firefox does not appear among the viewers offered. I'm not tech savvy, so a step by step (idiot's) guide as how I can gain access to and then make use of the Firefox as my default PDF viewer will be greatly appreciated, please.

Recently I have found that I cannot download statements from my bank account, also at the same time (2/3 months ago) I cannot access a Tesco website from Firefox. I can carry out these functions easily from Microsoft Edge, so why the sudden change ? Can anyone please help me to fix this in Firefox?

Automatic duplication of data from Cloudfare when I use my VPN

I've noticed that when I use my VPN the Broadband data volume measured by my Glasswire traffic meter software monitor is doubled. I've tested it numerous times, and when I download a file it appears to download it automatically to Cloudfare as the volume is almost the exact double of the file size and double the amount as measured through my VPN. Could this problem be associated with the DNS over HTTPS feature. I've changed this setting so that Cloudfare doesn't load anything automatically, but there is no change. Is there another automatic Cloud setting I should change or could this problem be independent of Firefox. Thank you. -Reply to moderator Co-rel "answer": @Co-rel, You are not answering my question. And are you inferring there could be a bug in my Firefox version and I would need to debug it myself? I am asking if there is a default setup in association with Cloudfare which would record all of my traffic and/or downloads. I've canceled the default DNS to HTTPS Cloudfare default. Is there another automatic default service clouding to Cloudfare storing our data automatically built-in Firefox? My Traffic and Data Monitor Glasswire records or measures my traffic as anticipated when I browse without using my VPN. But when I use the VPN the data count is doubled and what newly appears on the register is the URL of Cloudfare which is the same size approximately as the file downloaded, doubling the traffic. I tested by isolating a simple maneuver of downloading a single 150 Mb file. I did it twice with the same result. I did the same thing twice with a 1 Gb file last Wednesday, got the same results.

Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.

WED 21FEB24 The urgent issue is that in the last few weeks, many web pages do not load content, just a grey or white screen. Some will load the header. I am the Executor for someone's estate, and I am having this trouble with some financial websites that I must access to do the job.

Its been many years since I upgraded anything. It might be that Macintosh Firefox 78.15.0 esr (64 bit) and Thunderbird 60.9.1 are the newest revs that work with OSX 10.11.6 El Capitan. I have a 2011 MacBookPro.

I don't like the changes in the user interface that Apple put into OSX after El Capitan. But I may be forced to upgrade. Too late in life to learn Linux.

Maybe the minimalist solution is to upgrade Firefox. But that may require upgrading OSX, and Apple has made it really hard to do that unless you go to the very newest. OTOH I don't know if the newer OSX will run on my 2011 MacBook Pro. If I clicked on "software update" in About This Mac, what would happen? would it just start doing it, or tell me about it first?

The last time I upgraded something, probably Thunderbird but maybe it was Firefox, I had to learn a complicated process to copy & save the User Profiles (they are in a hidden directory), and then install them into the new rev. I don't want to go through that again. I just want to run the dmg file.

There used to be a Mozilla web page with all the versions & you could download the dmg file you wanted.

If I still have problems, I would have to buy a much newer computer. A several year old MacBookPro. But I don't like the "new" disk formatting method Apple created. It saves space by not actually making copies of files, but uses a pointer to one copy. So there is a single point of failure, which makes copies pointless. I want to keep using OSX Extended (Journaled) and I would have to have the seller of the computer do that for me, before I used Migration Assistant to put my stuff on it. I also hate the welded-on hard drive; being able to pull the drive is the best "broken hardware" solution.

I don't recall if El Capitan has the "OSX Recovery" system or if that happened in a later rev.

I use SuperDuper to make a clone of my hard drive as a backup & archive. I wonder if I could connect a copy on an external drive and then startup using the external copy. Then I could upgrade Firefox and see if it works, then do the same for OSX if necessary, and Thunderbird.

Suggestions & how-to info needed. TIA

I had posted my question yesterday and received a response from jscher2000. I sent a reply to the response by email a short while ago, but I wasn't sure it went through. Therefore, at the possible expense of having you receive the reply twice, I have recopied it here:

Thank you for trying to help me download Firefox onto my computer. As per your advice, I first tried shutting down and restarting my computer. That did not work. Then I went onto the link you sent me: https://www. mozilla,org/en-US/firefox/all/#product-desktop-release . The installation began, but only got up to around 80 - 90%. It stopped at the point where it said Execute: "C:|Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046B... (It looks like there might be some more letters and/or numbers after the "B", but I can't see what they are.) I waited a few more hours to see if the installation would continue, but it did not. I then went back to try downloading Firefox in the regular way. First I got a message, "Now installing. Firefox will be ready in just a few moments." Again, installation proceeded to around 80 - 90 %, and then I got a message, "Hmmm. For some reason, we could not install Firefox. Choose OK to start over." Starting over didn't help. I got the same message. Any further help or advice that you can give me would be greatly appreciated. drzee1946 email: [removed from public support forum]

After wipe of drive and reinstallation of Ventura by the Apple Store, and migration from Time Machine, Firefox won't launch. It's there, but it won't open. Click the icon and the icon moves as if it were going to launch, but the app doesn't open. If I were to reinstall Firefox, would it sync with my settings and Bookmarks?
