Diễn đàn hỗ trợ Firefox

A few days ago I started to get random popup ads. All of a sudden an ad will op up that says something like "you are at rusk, get Macafee" or "get Norton" etc. The ads pop up in the center of my screen and are about 20% the size of my screen. I have to click the x to get them to close. Sometimes there is the "don`t show me this again" option at the bottom left but even when I click ok the ads continue to pop up.

I`ve tried a few things but can`t figure it out. I`m retired and not a geek so it can get pretty frustrating pretty quick. I`ve lost my patience to scour through help articles looking for the exact sentence I need.

A step by step tutorial would be nice, thank you. I am using a laptop with windows 8.1. I use Firefox.

Thanks David

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

Thanks to Proton expanding my Bookmarks Menu off the bottom of the screen, I was re-arranging my bookmarks folders. While wondering which of my folders I had to prune, I noticed another in-built redundancy. The entry "Manage Bookmarks Ctrl+Shift+O" appears twice, at the top and the bottom of the menu. Incidentally the bottom entry is misaligned (Firefox v89 on Windows).

Is there a particular reasons for this duplication? Can I remove either of these entries?

I just got my upgrade from Firefox86 to Firefox90 working, but the tab bar is completely missing.

I still use "old-style" FIrefox. From top to bottom: File/Edit/View menu Search bar Bookmarks Toolbar Tab bar

(yes, I AM old. I've been using Firefox since Version 1 and this particular style works for me, developers be damned.)

The tab bar is completely missing. Firefox knows how many tabs I have open (it warns me when I try to exit) but doesn't show any. The area that the Tab Bar used to occupy is simply empty.

Any ideas on how to fix? (Yes, I have done the Google.)

All my bookmarks have disappeared from bookmarks. I restored bookmarks in the menu folder but my bookmarks in the bookmarks toolbar are still missing. How can I get my bookmarks in my bookmarks toolbar back?

Hello, I am still using windows 8.1 64bit & refuse windows 10, due to high risk privacy, yes predictable hollow words are said, BUT is Microsoft, a greedy un-scrupled money making, money hungry corporate entity, wants us to willing give it our private details voluntarily or under thin layer of extortion.

Hence my sticking to windows 8.1 as I have certain control, mainly updates.

Will Mozilla browsers be specifically supporting older operating systems like windows 8.1 into the coming years, not just months, e.g. until January 2023

Yes is a blunt question, but is eluded against in other responses, maybe is Microsoft buy out to sacrifice mozilla loyal users or similar, same query is for Brave browser. Mozilla I think is last Bastian for decency & morality, a leader in justice & honour.

I'm having a problem selecting articles that I would like to share with personal friends - i.e. grandaughter to their e-mails. (Not Facebook or Twitter, etc.). This used to be available but not accessible now. Some websites have this feature, but others do not.

Please advise. Betty

I am working in firefox 100.0.2(64-bit). While loading files from the input element the file.type of a .csv file shows application/vnd.ms-excel instead of text/csv. What could be the problem here? It works perfectly fine in chrome.

Hi,

I downloaded the new Firefox browser a couple of days ago and now I have lost all my bookmarks.

Does Firefox have a recent backup that I can import?

I clicked on 'Bookmarks', then 'Manage Bookmarks', select restore, but the bookmarks are from months ago.

Where are my current bookmarks?

Also, where is the bookmarks icon which was in the top right-hand corner, how do I access the bookmarks in this new version?

Kind regards,

Maria

I've purchased a new computer and I'm wondering how to transfer all my bookmarks to the new one. WIll they automatically transfer when I install Firefox in the new device when it recognizes my email

I recently had to reinstall firefox due to a few issues. Before the reinstall, when I opened a new tab it would open as my home page. After I reinstalled it, I was able to set up my homepage URL but there is no option for new tabs to open wth the same page. The only options for new tabs are blank page or the default firefox homepage. This was never an issue before the reinstall.

How do I fix this? Has the option been moved somewhere else?

Hey !! Mozilla, I just updated ....What happened to the compact mode for Bookmarks..Now they are double spaced they take up too much room.. Bring back compact mode or I will have to find another browser that enables a compact mode. Infuriating.

I just tried to open a new window using File, New Window. It is GONE. I always use that. Now all I get are New Tab New Container Tab (grayed out so I can't select that) New Private window, some other stuff.

The same is true if I right click. I get: Open Link in New Tab Open Link in New Private window.

What did I do to cause these changes?

Hi. Today after booting up the laptop I got the message in the screenshot from Avast antivirus. Can you help me determine whether it is a false positive? I opened firefox once, I had no connection to the internet (website not found errors), then closed firefox, opened it again and then the message popped up.
