Firefox Community Forum

Hi,

I'm working on a Firefox extension where I need to detect print event. I've tried the following approaches:

• beforeprint – Fires immediately when the print dialog opens (works correctly in Chrome).
• afterprint – Fires immediately when the dialog closes (works correctly in Chrome).
• window.focus and visibilitychange – Work inconsistently with noticeable delay, depending on how Firefox handles focus/visibility updates after closing the dialog.

Questions: 1. Is there a reliable way in Firefox to detect print event? 2. Are there any known workarounds or events that could be used for this purpose?

Thanks.

I'm expressing a strong dislike for the very shortened list of paper sizes in Firefox in the Print function.

One big reason I use Firefox over Chrome and MS Edge is the long list of paper sizes. Now the list is a small fraction of what was there. And how many people know what sizes are the likes of A4, B3, JIS-B4. It takes extra time to figure out what works best.

The old list with Letter Plus, Letter Extra, Legal Plus, etc. was MUCH MORE useful. If I were to eliminate anything, it would be the meaningless A5, B5, etc.

At least give us an option of the old or too short new list of paper sizes.

If my comments aren't appropriate in this forum, please provide a link to where I can submit it.

When I print an email to PDF the default folder destination is stuck on this one non existent folder. I can change the destination, but the next time I do this the default has reverted. I save a lot of emails this way & this new development is not only costing me time but is aggravating as can be. Before this situation developed the defalt destination would be the last folder I saved to. That is what I want to get back to. Anyone have a suggestion?

Good afternoon. Since recently (probably after the last Firefox update to version 136.0) I have a problem: every time I start Firefox it requires the main password set in the settings. Before this problem did not occur, no settings were changed.

I read the official article on this topic, but the recommendations described there did not help me. I turned off the password, logged out of the browser, turned it back on, logged out again, and nothing. When I turned it back on, still at every startup it asked for the password.

I also noticed that every time I start it up, the loading circle next to the cursor spins, like something is happening. Can you tell me what it could be and how to get rid of this problem?

With update 136.0, FF is requiring us to use a master password. I have one already set so my data is protected. I do not need a master password to open FF, but now I do.

Viewing my online banking register there is an option to printout a selected transaction. The print dialog comes up, the intended page flashes for a split second, and disappears. Selecting Print in the dialog box doesn't print anything. This is a recent development. A few versions ago, there was no issue.

I have to start Safari to get my printout. -(

I tried to print directly from a website, but it will not print. If I print an image or PDF, it will print just fine. I am currently using Firefox 135.0.1 on a macOS Sequoia 15.3.

Current version of Firefox from 2025, when I save as the screen is maximized without the conventional restore maximize icons in the top right corner of the window the way it's been for the last thousand years or since Windows 95. I found an old post that solved the problem which is, right click on the top menu and you'll see a drop-down restore move size maximize close. Well that's great but that is a Firefox concoction that is not standard practice. Fine to keep it but can you please also add the normal icons that we've all been used to since the beginning of the computer era? Thank you
