Desktop Firefox lacks a menu option that turns the current page into a QR code, and many of the add-ons that fill that gap ask to read and change data on every site you visit. MakeQR is a web page, not an extension, so it opens in a Firefox tab and works as it does in Chrome or Safari.
Paste the link and the code is drawn in your own browser as you type. A static code is made entirely there, and nothing you paste is sent to a server. What comes out is an ordinary QR code, as a PNG or SVG file, readable by any phone's camera, and it keeps working after the tab is closed.
Turn a Firefox tab into a QR code
Copy the address from the bar
Click into Firefox's address bar (or press Ctrl+L / Cmd+L), select the full URL, and copy it. If the page carries a tracking parameter after a question mark, decide whether that part needs to be there — most of the time it doesn't.
Paste it into MakeQR
Open makeqr.ai in the same Firefox window and paste the link into the web address field. Nothing you paste leaves your browser until you choose to download the finished image.
Pick static or dynamic
A static code is free and fixed to that exact link forever. A dynamic one opens a short MakeQR link you can repoint later, useful if the page you're sharing is likely to move.
Download and check the print preview
Download SVG for anything going to a printer, PNG for a screen. If you're printing straight from a Firefox tab, open Print Preview first and confirm the code isn't shrunk to fit a scaled page layout.
Why you don't need a Firefox add-on for this
Firefox's add-on store lists several QR code generators, and most ask for the same broad permission: read and change the data on every site you visit, so they can grab the current tab's address automatically. That's a lot of access for something a copy and paste does just as fast. MakeQR never sees your browsing at all, it only receives the link you type in, and there's no extension to update, lose to a Firefox version change, or find abandoned by its developer a year from now.
Scanning a code while you're the one browsing
Firefox's desktop browser has no built-in camera scanner. If you're on the receiving end of a code, someone hands you a flyer while you're at your laptop, MakeQR's browser scanner reads it from an uploaded photo or a webcam, shows where it points, and only opens it if you choose to. It works in Firefox the same way generation does, with nothing to install.
Printing straight from a Firefox tab
If the code sits on a page you built and you're printing that page directly from Firefox rather than a separate design file, check the print preview at actual size before running a batch. Firefox's preview sometimes shrinks a page to fit the margins by default, and a code printed under 20 mm wide is a common reason a poster or flyer fails to scan from across a room.
What's actually inside the code
For a browser tab, the code almost always encodes a plain web address: the exact text from the address bar, nothing more. MakeQR reads the pattern back after building it and shows a warning if the colors chosen are too close together for a phone camera to separate.
https://example.com/support-pageWhere a browser-tab code ends up printed
A code built from a webpage link usually leaves the screen entirely: a handout, a poster, a business card, or a sticker on hardware pointing to a setup guide. Keep the scanning-distance rule of roughly ten to one — a code meant to be read from about a meter away needs to be close to 10 cm across, and one on a business card should still print at least 20 mm.
Print it at least 20 mm (2.0 cm) wide
Mistakes that come from copying straight out of the address bar
Encoding a link with a login session in it
A URL copied while signed in can carry a session token after the question mark. It works for you and fails, or opens someone else's account view, for the person scanning. Strip anything after a question mark unless you know what it does.
Pointing at a local address
Testing on localhost or a private network address such as 192.168.x.x produces a code that only works on your own network. Publish the page first, then encode the public address.
Trusting a shrunk print preview
A code that looks fine on screen can be too small once a page layout is scaled down to fit a printer's margins, so check actual size before a full run.
Static works for almost every browser-tab link
Most pages shared this way already have a permanent address, so a free static code is enough. Reach for dynamic only if the link is likely to change, such as a temporary campaign page you'll eventually retire.
How dynamic QR codes workWhere this actually gets used
- A support page's address printed on a product's packaging insert so a buyer can find setup instructions from their phone.
- A conference schedule page turned into a code on a handout, generated the same day it goes to the printer.
- An internal wiki page linked from a sticker on shared office equipment.
- A blog post shared as a code on a printed zine or flyer.
