Diễn đàn hỗ trợ Firefox

Hi. Yesterday, I browsed thru my Firefox and/or GMail settings, and removed headers and footers from my printed copies of emails and web pages. Which is fine. However, at the same time I must have mistakenly changed a setting so that my print-ready version of an email or web page always displays in B & W, not in color. Although it will print in color, depending on how I have my HP printer set. How can I change that back so the print-ready Print Preview copy displays pics, etc. in color? I forgot what I did. Aarrgh! Please help! Thanks. John Darin

I see that someone has changed the 'Print' feature. Previously, when I wanted to print something from a website, the print feature gave me the option of 'simplifying the page', which reduced the number of pages to be printed significantly. I have tried printing out 2 pieces of information recently and could not find the 'Simplify page' feature. Has this been removed; and, if so, why?

Recently, I noticed Firefox has a new printer dialogue box. When that dialogue box starting showing up, all of my two-sided print jobs are BACKWARDS. The back page is flipped 180 degrees from the front page. WRONG!

As a sanity check, I double-checked with Chrome and Opera. No problem. Double-sided print jobs print as usual (i.e., when you flip the page over in the horizontal direction, the print orientation remains correct).

Somehow, the new Firefox Browser printer dialogue overlay is overriding the HP printer driver. Please fix!

Nothing will open. Not even settings. Just a blank page. Won't go to any web pages. I uninstalled and reinstalled, same thing. Almost like an update messed it up, but I looked in Windows update and there were no recent updates. Microsoft Windows 10 Home.

Recently when clicking on a link in an email, a new Firefox browser opens rather than the clicked website being added to the already open browser. How do I set email links to be added to the already open browser as has been the case for a long time? Thank you

I have no idea how it started or why, but in the past couple days anytime I leave my cursor over a paragraph or chunk of text on a website, a black box appears where my cursor is with the text in it in white. If there is a lot of text, there's a sidebar to scroll down in the box. This disappears as soon as I move my cursor, but reappears as soon as I set it near some more text. I assume this is some kind of accessibility or reading feature, but I have no idea how I turned it or how to get rid of it. I've looked online and in my setting and had no luck getting rid of it. Any help would be appreciated!

How much is Firefox OR is it totally free?

Firefox 86.0 (64-bit) on macOS

When I start to type the URL for an address I use often, for example bar for barnesandnoble.com, I always get barefootyoga.com as a suggestion. I've never visited this website. It's not in my history. I have no idea what it's popping up when typing bar used to autofill barnesandnoble.

When barefootyoga pops up in the URL as a suggestion, I click SHIFT + DELETE, but barefootyoga appears the next time I type bar. (This is happening for almost all other websites where autocomplete used to work correctly--this is just one example.)

I've cleared all history for all time and restarted browser. Same result. After relaunch, I fully typed barnesandnoble.com and visited the website to get it back in history. I opened a new tab, typed bar, and barefootyoga began to autocomplete

In Preferences, I get the same unwanted result with these settings: Search > Search Suggestions > Disable/renable "Provide search suggestions" Privacy & Security > Address Bar > All check boxes selected except for search engine In about:config, I scanned options for browser.urlbar, but nothing looks like it would resolve this issue

I feel as if I am missing something obvious.

Hello,

this knowledge base article (Remove the Other Bookmarks folder from the Bookmarks Toolbar) claims that you can display the Other Bookmarks folder on the toolbar since Firefox 85 but it seems to be a lie.

In the screenshots down below, you can see my current settings. The Other Bookmarks folder is missing although my settings are correct.

How can I display the Other Bookmarks folder on the toolbar in Firefox? Thanks for your help!

I'm trying to view Livescience.com and this is all I get: "AD BLOCKER INTERFERENCE DETECTED, please disable or whitelist" how do I fix this? There's nothing in my add-ons or extensions to change this. Thanks!

I've done all that Firefox suggests but I always have to fill in my login details at every site. How do I get Firefox to automatically offer my login details to login?

I want to change my default search engine, but for some reason the drop-down menu on the preferences pane doesn't recognize Duck Duck Go or any other option other than Google. I just rebooted my computer and still it doesn't work. Please advise.

Problem

For the last few versions, opening Firefox would result in no pages loading. The tabs would keep spinning with no result.

I've disabled plugins to find the cause, and have found that I can't reproduce this issue with no plugins enabled, but can reproduce this issue with only the Firefox Multi-account containers plugin enabled.

This problem also doesn't happen if I delete rm -rf ~/.cache/mozilla/firefox/*.default-release before starting Firefox, even with the plugin enabled.

When I have this problem, I can disable the Firefox Multi-account containers plugin to get the tabs to load, and then re-enable it. This implies the plugin is somehow blocking the tabs from loading.

Thank you for taking the time to read this question. Let me know if you would like any more information.
