How to clear your Cache and Cookies in Firefox

May 29, 2021 by Jay Versluis

Cookies can be the downfall of every healthy web browser. Just like humans eat too many cookies, browsers can develop serious unreasonable issues when ingesting too much. I always forget how to clear them out, so I thought I’d make a note here. Doing this from time to time has greatly helped me cure anything … Read more

How to avoid Firefox from opening on random desktops on macOS

March 4, 2021 by Jay Versluis

I’m a Firefox user, have been for years. Updates are happening hard and fast, and as such sometimes – and I guess inevitably – things stop working they way they used to before an update. Did I mention I genuinely and passionately HATE updates? Well one such update recently meant that Firefox no longer opens … Read more

How to switch Firefox to Dark Mode permanently

November 18, 2020 by Jay Versluis

Firefox acknowledges the operating system theme changes by default. This may not always be what you want. There’s a whole host of themes we can use, and this feature is right built in to Firefox. It’s so un-obvious that no ordinary user would ever come across it though, so I thought I’d let you know … Read more

How to re-open a closed Tab in Firefox

September 9, 2020 by Jay Versluis

Hey I’ve been there more times than I can count: close one or several tabs, only to think, “dang – I needed to keep that one open. What was that URL again?” Looks like I’m not alone, because many browsers support a feature that lets us re-open an accidentally closed tab. I use Firefox, and … Read more

How to switch from JFIF to JPEG on Drag-and-Drop in Windows 10

January 11, 2020June 26, 2019 by Jay Versluis

I’ve recently noticed that when I drag an image out of Firefox, it saves itself as a JFIF image on Windows 10. Choosing to save the same image via the right-click context menu will save it as JPEG image as expected. This perplexed me, so I did some research and found a fix that would … Read more

How to reactivate Easy YouTube Video Downloader for Firefox

May 20, 2019 by Jay Versluis

There’s a really useful Firefox plugin called the Easy YouTube Video Downloader by Dishita. Here’s the direct link on the Firefox Add-Ons Directory. Once installed, it allows you to download MP4 and MP3 versions of any video on YouTube. That’s super handy if one my streams is not recorded properly at my end. Let me tell you, it’s always good to have a local backup of things!

With the free version we can download MP3 files in 128Kbps and MP4 files in 720p. Higher resolutions are available with the Pro Version, for which you can make a voluntary donation. It’ll work immediately after you’ve made a payment, by clicking a link provided to you via email.

Trouble is, every once in a while (usually after a Firefox update), the Pro Version reverts back to the Free Version, and you’re stuck without all your paid for Pro Features. How do we get them back without paying again?

I’ve just found out – and I thought I’d remind us all how this works.

How to install the British Spell Checker in Firefox

January 9, 2019 by Jay Versluis

I admit my language needs are a little bit less “normal” than those of most people:

I live in the US, I write things in English most of my time, but I’m used to writing with British spelling and grammar – and occasionally I write in German too. So that makes managing languages on the myriad of devices I’m using sightly tricky.

In this article I’ll show you how to change your language settings in Firefox.
