I see it as well. If I had to guess, I'd imagine it is a dev feature built into Lemmy UI for debugging on mobile that was mistakenly left on.
Yes, i think i have this too. I am using firefox for android. It appears like a settings button but it allows me to do inspect element. No idea why its there. I came to post about this but i'll join your post.
Are you as annoyed as I am lol?
It's sonething I turned on to debug lemmy and forgot to turn off. Sorry!
All good! Was only going crazy because it felt like I was being told it was something I must have done haha.
It appears to be a shortcut to the developer tools built into the browser. Either somebody added it to the page or you installed it yourself mistakenly or otherwise.
I see it on both Firefox for Android and Firefox for Linux when browsing this instance. It does not appear on Lemmy.World for example. It also does not appear to use the browser's dev tools as I am able to open both Firefox's native dev tools and Eruda at the same time and they look different.
I did not install it mistakenly myself (only saying this as I haven't left lemmy on this browser in 2 days) or if I did I am not sure how as I have not visited github or any of the websites. I cannot find any addon listing, download, nothing.
She’s a witch!
